Question

The table below shows the values of y for each value of x:


x
y
1
0
1
-1
2
1
2
-2


Part A: Does the table represent a relation that is a function? Justify your answer by using the values shown in the table. (4 points)

Part B: The function f(x) shown below represents the number of baskets Jess made at different distances, x, in meters, from the hoop:

f(x) = -x + 6

Calculate and interpret the meaning of f(4). (4 points)

Answer 1

Part C: Write an ordered pair to represent the input and output of the function in Part B when Jess is at a distance of p meters from the hoop. (2 points)

Answer 3

I can't see the table good enough.

Answer 4

Can you fix the table? @domisreallytall

Answer 5

x=1,1,2,2
y=0,-1,1,-2

Answer 6

The table is NOT a function because you cannot have two of the same values of x with two different values of y.

Answer 8

That answers Part A for you @domisreallytall

Answer 9

@iGreen

Answer 10

Calculate and interpret the meaning of f(4).

f(4) would mean to input 4 for x,

So in the equation f(x) = -x + 6, you will input 4 for x and get:

f(4) = -(4) + 6

Answer 11

Okay, that's Part A & B answered.

Answer 12
