Function or Not 

No, -7 gives two different outputs

100

Is this a function?

Yes, it passes the VLT

100

What is the y-intercept of the function:

y = 2/3x - 10

-10

100

Evaluate the function at x = 2

y=3x+10

16

100

When was this person standing still?

5 - 9 seconds

200

Function on not?

X is not repeating, automatically YES

200

No, it doesn't pass the vertical line test.

200

What is the function rule for the graph?

y=-1/2x-3

200

Evaluate 

f(3)=4x-1

11

200

When were they walking the slowest?

11 - 18 seconds

300
