DISCOVER: Transformations of y = 1/x2 In Example 2 we saw that some simple rational functions can be graphed by shifting, stretching, or reflecting the graph of y = 1/x. In this exercise we consider rational functions that can be graphed by transforming the graph of y = 1/x2.
- (a) Graph the function
by transforming the graph of y = 1/x2.
- (b) Use long division and factoring to show that the function
can be written as
Then graph s by transforming the graph of v = 1/x2.
- (c) One of the following functions can be graphed by transforming the graph of y = 1/x2; the other cannot. Use transformations to graph the one that can be, and explain why this method doesn’t work for the other one.

If the problem can be solved using precalculus, solve it. If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution. STEP 1: Consider the figure in part (a). Since this region is simply a triangle, you may use precalculus methods to solve this part of the problem. First determine the height of the triangle and the length of the triangle's base. height 4 units units base 5 STEP 2: Compute the area of the triangle by employing a formula from precalculus, thus finding the area of the shaded region in part (a). 10 square units STEP 3: Consider the figure in part (b). Since this region is defined by a complicated curve, the problem seems to require calculus. Find an approximation of the shaded region by using a graphical approach.
