Which Statement is NOT always true?
A). The inverse of a linear function is a function?
Not true when the linear function has slope 0.

B). The inverse of a quadratic function is not a function ?
Always true because a parabola does not pass the horizontal line test.

C). If a function has two x-intercepts, then its inverse has two y-intercepts ?
Always true, although the inverse is not a function.

D). The inverse of an exponential function is a logarithmic function ?
Always true.
