The function g(x) is a piecewise function For x 4, 1 g(x) = |x + 1| and for
x 1, 3 g(x) = 2.
What are some rules for the transformation of functions?Suppose we have a function f(x).
f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).
f(x ± c) = Horizontal left/right shift by c units (x - + c, y).
(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).
f(bx) = Horizonatal compression b > 0, horizontal stretch for b < 0. (bx , y).
f(-x) = Reflection over the y-axis, (-x, y).
-f(x) = Reflection over x-axis, (x, -y).
From the graph, we can conclude that g(x) is a piecewise function.
When x is - 4, 1 g(x) = |x + 1|.
And when x is 1, 3 g(x) = 2, A constant function.
Now, g(-2) = | - 2 + 1| = 1.
g(1) = | 1 + 1| = 2.
g(4) = 2.
The value of x when g(x) = 3 is - 4.
The value of x when g(x) = 1 is (0, - 2) as both satisfy g(x).

Answers
The equation that defines the graph y=x³ after it is shifted vertically 5 units down and horizontally 4 units left is y =( x + 4 )³- 5.
What is a graph?A function is truly equal to its graph in the modern mathematical foundations and typically in set theory. However, it is frequently helpful to think of functions as mappings, which include not just the relationship between input and output but also the sets that make up the domain and codomain. For instance, it is important to consider the codomain while determining whether a function is onto (surjective) or not.
For k=- 5, y=f(x) + k represents a vertical shift down.
For h=4, the horizontal shift left is y=f(x+h).
Therefore, the equation that defines the graph y=x³ after it is shifted vertically 5 units down and horizontally 4 units left is y =( x + 4 )³- 5.

A right triangle has legs of 30 inches and 40 inches whose sides are changing. The short leg is increasing by 5 in/sec and the long leg is shrinking at 7 in/sec. What is the rate of change of the hypotenuse?
Answers
That is a change in the hypotenuse's length of -2.6 inches per second.
What in math is a rate?
A rate is a unique ratio where the two words are expressed in several units. For instance, the price is 69 for 12 ounces if a 12-ounce can of maize costs 69. This is not a proportion of two comparable units, like shirts. This ratio compares two dissimilar units: ounces and cents
h = sqr(b^2 + a^2), b=30, a=40, b'=-5, a'=-7
h' = [(1/2)/sqr(b^2+a^2)](2bb' + 2aa') = sqr(30^2+40^2)(30(5)+40(-7)
= (150-280)/sqr2500 = (-130)/50 =-- -13/5 = -2.6 inches per second
2.6 inches are lost from the hypotenuse every second.
Check the response by observing what transpires in one second.
30 to 35 on the short leg
greater leg descends from 40 to 37
From 50 to 47.4 is the hypotenuse
In one second, 50-47.4 equals a 2.6 reduction. That is a change in the hypotenuse's length of -2.6 inches per second.

What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
Product B performed worse in the study because 32% failed to get relief with this product, whereas only 28% failed to get relief with Product A.
Working through this, the percentage who failed to find relief from product A is (25 - 18) / 25 = 28%. Doing the same type of calculation for product B, we can determine the percentage who failed to find relief as (50 - 34) / 50 = 32%. The description statement asks for which offered less relief, which we can find using the less than operator:
28% < 32%
Product A offered relief to all but 28% of the people, while product B offered relief to all but 32% of the people. Given that fewer people failed to find relief on product 28%, we can argue that more people did find relief on product A.
Given that the tests are both on multiples of 25 people, we can also see the percentages by multiplying the numerators and denominators to bring both to a scale of 100:
7/25 * 4/4 = 28% of product A users failed to find relief.
16/50 * 2/2 = 32% of product B users failed to find relief.

Answers
Kara erred when she answered the equation 2x + 6 = -8. Instead, she should have solved the equation 2x + 6 = 8 because it relates to the second situation (where -2x + 6 + 10 is smaller than 0).
Kara made a mistake when solving the equation |- 2x + 6 + 10| = 2. The correct steps to solve this equation are as follows:
First, we need to find the value of -2x + 6 + 10. To do this, we need to remove the absolute value bars by considering two cases:
a. If -2x + 6 + 10 is greater than or equal to 0, then the absolute value is equal to -2x + 6 + 10.
b. If -2x + 6 + 10 is less than 0, then the absolute value is equal to the negative of -2x + 6 + 10.
In the first case, we have -2x + 6 + 10 = 2. Solving this equation gives us x = -1.
In the second case, we have -(-2x + 6 + 10) = 2. Solving this equation gives us x = 7.
Therefore, the solution to the equation |- 2x + 6 + 10| = 2 is x = {7, -1}.
She made a mistake when she solved the equation 2x + 6 = -8. She should have solved the equation 2x + 6 = 8 instead, because this is the equation that corresponds to the second case (where -2x + 6 + 10 is less than 0).
As a result, Kara got the wrong value for x and included the incorrect solution {7, -1} in her final answer.
