−∞<x<∞
{ -2, -1, 0, 1, 2 }
Is the relation function?
Yes
No
Determine which graph/s define a function?
No
What is the domain of the given function?
{ ( 0, -1 ) , ( 2, -3 ) , ( 3, -2 ) }
{ 0, 2, 3 }
{ -3, -2, -1 }
The equation below describes a function of x.
y=5x−7
What input value in the domain corresponds with
an output value of 3?
A furniture store delivers for $40 plus $0.75 for every mile they have to travel from the store.
Write a function that represents the cost for delivery, c(m), given the distance from the store, m, in miles.
c(m) = 0.75m
40 = 0.75m
0.75 = 40m
c(m) = 40 + 0.75m
A furniture store delivers for $40 plus $0.75 for every mile they have to travel from the store.
Given the function c(m) = 40 + 0.75m, how much does delivery cost for someone who lives 60 miles from the store?

f(0)=3
f(0)=6
f(3)=0
f(6)=0
