evaluating linear functions and graphs

The function c(m) = 1.45m + 3.50 represents the cost of a taxi for m miles.

What does c(7) represent?

• A cost of $7 to ride the taxi

• The cost to ride 7 miles

• The minimum distance to ride a taxi

• The minimum cost of a taxi

• f(-2) = -1

• f(-2) = -9

• f(-2) = 9

• f(-2) = 0

Evaluate f(-3)

• f(-3) = -3

• f(-3) = 0

• f(-3) = 2

• not enough information to give an answer

What is the missing number?

• 12

• 10

• 14

• 13

• f(-2) = -1

• f(-2) = -9

• f(-2) = 9

• f(-2) = 0

f(x)=4x+5
f(4)=
