is the relation shown in the arrow diagram a function? explain
Input 1 3 4 3
Output 1 9 16 27
A.yes each input has only one output
B. yes each output has only one input
c.yes each output is the square of the input
D. no the input 3 has 2 outputs

Answers

Answer 1
Something can be described as a function if there is only 1 of each number in the input or x.
For example: (9,6) and (9,3) would not be a function because there are two 9’s as the input.

So, for this problem there are two 3’s meaning this is NOT function because there are two outputs for the same number.


Your answer is going to be D.
Answer 2

The given relation is not a function because input value 3 has 2 outputs.

What is Function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

Input 1 3 4 3

Output 1 9 16 27

A relation is a function when the inputs are distinct and have corresponding output.

So, the given relation is not a function because input value 3 has 2 outputs.

2m + 14 − 15 − 15m simplified

Answers

-13m - 1 is the simplified equation !

Answer:

-13m-1

Step-by-step explanation:

You want to combine all like terms

In this case, that would be 2m, -15m and 14, -15

When you add 2m to -15 m, it gets you to -13. Similarly, you can subtract 15 from 2, and get -13 as well. It depends on which method you prefer.

Then, you want to combine 14 and -15 using addition or subtraction. Add 14 to -15 and that gets you to -1. You can also subtract 15 from 14 and get -1 as well.

Answer:

Step-by-step explanation:

For adding negatives, you basically just subtract. For example, -3+5. To find the answer, you subtract 3 from 5, leaving you with 2. For decimals, you add like normal, but you carry the decimal down, and leave it in the same place.

Answer:

69.77

Step-by-step

1. Put the numbers in a vertical column, aligning the decimal points

2. Add each column of digits, starting on the right and working left. If the sum of a column is more than ten, "carry" digits to the next column on the left.

3. Place the decimal point in the answer directly below the decimal points in the terms.

laps does Lilliana run on Saturday?

Answers

Answer:

6 Laps

Step-by-step explanation:

Each lap is 2 Miles.

If she runs 2 laps and runs 8 more, 2x2 = 4.  8 + 4 = 12

If she runs 4 laps and 4 miles, 4x2 = 8. 8 + 4= 12

On Saturday, she has to run 12 miles so 6 x 2 = 12

She would have to run 12 laps.
