Inverse Functions

Front

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

Back

(4, 1) and (6, 4)

Front

Find the inverse of
f(x) = 1/4x - 7

Back

Front

What does it mean to find the inverse of a function?

Back

the x's and y's are switched

Front

The inverse has been reflected over which line? Options: y = x, y =1, y = 0, y = x + 1

Back

y = x

Front

If f and g are inverse functions, and
f(2) = -1     g(1) = -2     f(1) = -2,
then which of the following MUST be true? Options: g(-2) = -1, g(2) = 1, g(-2) = 1, g(1) = 2

Back

g(-2) = 1
