What is the proper notation for the inverse of a function?

• f(-1)

• f-1

• f ^-1

• f(inverse)

Find the inverse of the function f(x)=3x-6. [Remember f(x) is the same as y.]

• f^-1(x) = ⅓x + 2

• f^-1(x) = x/6 + 3

• f^-1(x) = ⅓x - 2

• f^-1(x) = ⅙x + 2

Use the graph to determine whether the inverse of f is a function. Explain your reasoning.

• The inverse is not a function because f does not pass the horizontal line test.

• The inverse is a function because f does not pass the horizontal line test.

• The inverse is not a function because f passes the vertical line test.

• The inverse is a function because f passes the vertical line test.
