The inverse has been reflected over which line?

• y = x
• y =1
• y = 0
• y = x + 1

Use the horizontal line test to determine if the function has an inverse function.

• yes

• no

If the equation of f(x) goes through (1, 4) and (4, 6), what points does f^-1(x) go through?

• (1, 4) and (4, 6)
• (-4, -1) and (-6, -4)
• (-1, -4) and (-4, -6)
• (4, 1) and (6, 4)

TRUE or FALSE?
If f(g(x)) = x, then f and g must be inverses of one another.

• TRUE
• FALSE

Are f(x) = x + 6 and g(x) = x - 6 inverses?

• Yes

• No

Find the inverse: f(x) = x³ - 1

• f^-1(x) = ³√x + 1

• f^-1(x) = ³√x - 1

• f^-1(x) = (x-1)/3

• f^-1(x) = (x+1)/3

To prove two functions are inverses of each other, both f(g(x)) and g(f(x) should equal...

• x

• 0

• y

• -1
• 1
• -1/3
• -5/3

• 9 - √17
• 4
• 2
• √8
