x = -16

*13 is my favorite number

300

f(x) = x + 4 

Evaluate f(-2)

x = 2

400

h(x) = x - 2x + 3 

Evaluate h(3)

x = 0

500

g(x) = 2x - 12 

Evaluate g(3)

x = -6

Solving Functions

100

f(x) = 2x + 1 

Solve when f(x) = 11

x = 5

200

f(x) = -4x - 2 

Solve when f(x) = -22

x = 5

300

f(x) = x + 1 

Solve when f(x) = 26

x=25

400

g(x) = 4x - 10 

Solve when g(x) = -2

x=2

500

g(x) = 9x + 5 

Solve when g(x) = 32

x = 3
