22. Concept Check A quadratic function f(x) has vertex (0, 0), and all of its intercepts
are the same point. What is the general form of its equation?
Graph each quadratic function. Give the (a) vertex, (b) axis, (c) domain, and (d) range.
Then determine (e) the largest open interval of the domain over which the function
is increasing and (f) the largest open interval over which the function is decreasing.
