CCSS.HSA.APR.B.3

Determine whether or not the table represents a function.

• Function because the input of 3 has more than one output.

• Not a function because the input of 3 has more than one output.

• Function because none of the output values are repeated.

• Not a function because the number zero appears on the table twice.

What is the y-intercept of this function represented by the table?

• (2, 1)

• (0, -3)

• (-3, -3)

• There are no y-intercepts shown on the table

Based on the points you see on the table (-2, 7) is a _______. (If you are stuck, try sketching out the points and connecting the dots!)

• Maximum

• Minimum

• x-intercept

• y-intercept

Write the equation for the table given. (If you are stuck, try sketching out the points and connecting the dots!)

• y = 1/3x

• y = 3x

• y = -1/3x

• y = -3x

If f(x) = -3x - 8, find f(-1).

• f(-1) = 5

• f(-1) = -5

• f(-1) = -12

• f(-1) = -10
