11.4 Are functions inverses

What is the first step in finding the equation of the inverse of a function?

• get x by itself
• switch x and y
• solve for y
• write the function in inverse function notation

The inverse has been reflected over which line?

• y = x
• y =1
• y = 0
• y = x + 1

Are these functions inverses of each other?

• 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)

Was the inverse function found correctly?

• no,
• yes

• 9 - √17
• 4
• 2
• √8

When using composition to verify 2 functions are inverses, g(f(x)) and f(g(x)) must equal

• x

• y

• f(x)

• g(x)
