Inputs have different outputs every time

x-values and y-values

Is this mapping a function or not a function?

Function

Not a Function

Is the relation a function? Why.

Yes, because the x-value 11 has two y-values pair with it.

Yes, because each x-value has only one y-value paired with it.

No, because the x-value 11 has two y-values pair with it.

No, because each x-value has only one y-value paired with it.

The Roaming Cell Phone Company charges $15.00 per month plus $0.20 per minute of airtime usage. If Juanita uses x minutes of airtime, what is an equation that can be used to determine her monthly cell phone bill (C)?

C = 0.20x + 15

C =15 (0.20x)

C = 15 + x + 0.20

C = 0.20 + 15x

16.

Speedy Boat Rental charges a $15 deposit fee plus $2 for each hour of use to rent a paddle boat. Write an equation for C, the total cost, to rent the boat for h hours.

h = 2C + 15

C = 15h + 2

h = 15C + 2

C = 2h + 15

17.

Bob has $150 in his savings account and saves $40 per month. Which function models his savings?

y = 150 + 40

y = 40x + 150

y = 150x + 40

A man is climbing down from 100 feet high descending 30 feet per minute. Which function models his descent?

y = 100 - 30x

y = 100 + 30x

y = 100x + 30

y = 100x - 30
