Question

1. 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 function? Justify your answer by using the values shown in the table
No this is not a function because for it to be a function a value of x should pinpoint a value of y.
Part B: The function f(x) shown below represents the number of fieldgoals Frank made at different distances, x, in meters, from the post.
F(x) = -x + 8
Calculate and interpret the meaning for f(5).
Part C: Write an ordered pair to represent the input and output of the function in Part

@gorv someone help!

Answer 12

It is not a function. A function cannot have 2 or more x values that are the same. They can have 2 or more y values that are the same, just not the x ones.

f(x) = -x + 8
f(5) = -5 + 8
f(5) = 3

In a function, the input is x and the output is y.
f(x) is the same as y
so we have :
y = -x + 8 --- sub in any number you want for x and find y...lets try x = 4
y = -4 + 8
y = 4
One ordered pair is : (4,4)
