Tyra solved the quadratic equation x2-10x -24 = 0by factoring. Her work is shown below:
Step 1: x2-10x -24 = 0
Step 2: x2-4x - 6x - 24 = 0
Step 3: (x2-4x) + (-6x - 24) = 0
Step 4: x(x-4) - 6(x - 4)=0
Step 5: (x-4)(x-6)=0
Step 6: x-4 = 0, x-6 = 0
Step 7: x=4 or x = 6
Step 8: 4, 6

If f(x) = 42 - 5 and g(x) = 3x+ 7, which of the following statements are true?

I f(0) = g(-4)
II f(-2) - 9(2)
III f(0) = g(3)
IV f(6) - g(4)

Α. I only
B. I and IV only
C. II and III only
D. All are true

Answers

Answer:

B. I and IV only

Step-by-step explanation:

You replace the x with the numbers in the parenthesis. So for I it would be:

f(0) = 4(0) - 5 -> 0 - (-5) -> -5

g(-4) = 3(-4) +7 -> -12 + 7 -> -5

You solve each one and if your answer matches with each other, your answer is right.

If you did this with II and III, you wouldn't get the same answers.

For IV it would be:

f(6) = 4(6) - 5 -> 24 - 5 -> 19

g(4) = 3(4) + 7 -> 12 + 7 -> 19

Your final answer would be b 1 and 4

Given the function f(x)=(x+3)2-1, which of the following would describe a shift of the vertex 3 units to the left.

A. f(x + 3)
B. f(x)+3
C. f(x)-3
D. f(x-3)

Answers

Answer:

A. f(x+3)

Step-by-step explanation:

The vertex form is y=a(x-h)^2+k. To move left, your 'h' value has to be negative, so in this case, it'd be -3, but wait. Since it already tells you to subtract the 'h' value, subtracting -3, (-(-3), would be the same as adding 3. So inside the form, it has to be (x+3) to make sense. A is the correct answer.

B is incorrect because that just shifts the function 3 units up.

C is incorrect because that shifts the function 3 units down.

D is incorrect because that shifts the function 3 units right.

Hope this helps.
