If a given function f(x) has an inverse function g(x), which of the following statements is true?

• If (a, b) is on the graph of f(x), then the inverse graph of g(x) must contain (–a, –b).

• If (a, b) is on the graph of f(x), then the inverse graph of g(x) must contain (–b, –a).

• If f(x) has an x-intercept at (c, 0), then the x-intercept of the inverse graph g(x) must be (c, 0).

• If f(x) has an x-intercept at (c, 0), then the y-intercept of the inverse graph g(x) must be (0, c).

Determine whether or not the functions shown in the graph are inverse functions. Explain your reasoning.

• Yes , they are inverses. The inverse graph has the same opposite points.

• Yes, they are inverses. The graph does not reflect over y = x.

• No, they are not inverses. The points on the graph have the same opposite points.

• No, they are not inverses. does not reflect over y = x.
