6.1 - 6.6 Review A2H

Given
f(x)=3x²+7x and g(x)=2x²-x-1, find (f+g)(x).

• 11x² - 1
• 5x⁴ + 6x² - 1
• 5x² + 6x - 1
• 5x² + 8x - 1

h(x) = 2x² - x + 1

g(x) = 3x

Find (hg)(x).

• 5x³ + 2x² + 3x

• 2x² + 2x + 1

• 6x³ - 3x² + 3x

• 6x³ - 1

g(x) = x² + x - 2
Find g(x - 3)

• g(x - 3) = x² - 5x + 4
• g(x - 3) = x² - 7x - 14
• g(x - 3) = x² + x + 4
• g(x - 3) = x² - 6x + 10

f(x) = -4x - 12

What is f^-1(x)?

• f^-1(x) = 4x - 3

• f^-1(x) = -1/4x - 3

• f^-1(x) = 1/4x + 3

• f^-1(x) = -4x - 3

Which is f ^-1(x)?

• f ^-1(x) = 3x + 5

• f ^-1(x) = 3x - 5

• f ^-1(x) = 3x - 15

• f ^-1(x) = 3x + 15
