Question 1167086
<font face="Times New Roman" size="+2">


This function is quadratic, so the graph is a parabola.  The axis of symmetry divides the *[tex \Large x]-axis into two parts.  The half-open interval on either side of that point is a sufficiently restrictive domain for the function such that the inverse function exists.
