g(x) = 5 - 6x

Find g(-5) + 2

• g(-5) = -25

• g(-5) = 23

• g(-5) = 6

• g(-5) = 37

f(x) = 3x - 11 and g(x) = 1/2x+3

Find f(3) + g(4)

• f(3)+g(4) = 5

• f(3)+g(4) = 7

• f(3)+g(4) = -1

• f(3)+g(4) = 16

f(x) = x² - 2x + 1

Find f(0) - f(3)

• f(0) - f(3) = -3

• f(0) - f(3) = 3

• f(0) - f(3) = 4

• f(0) - f(3) = 0
