Mid Ch3 Review Inverse Linears and Quadratic Functions

If given function f(x), has an inverse function f^-1(x), which of the following statements is true?

• If (a, b) is on the graph of f(x), then the graph of f^-1(x) must contain (b, a).

• If f(x) has a y-intercept at (0, c), then the x-intercept of f^-1(x) must be (-c, 0).

• Both f(x) and f-¹(x) must have the same domain.

• If (a, b) is on the graph of f(x), then the graph of f^-1(x) must contain (-b, –a).

• If f(x) has a y-intercept at (0, -c), then the x-intercept of f^-1(x) must be (c, 0).

• The range of f(x) will be the domain of f^-1(x)
