Answer to Problem 3CFU
Choose a point on one side of the graph and solve the inequality for that point. If that point is a solution then that side or region of graph including that point will be shaded.
Explanation of Solution
Given information:
The condition is ‘the region of graph of an inequality to be shaded’.
Calculation:
The shaded portion of the graph includes all those ordered pairs or solutions satisfying that inequality. The procedure to select the region of graph of inequality for shading is to choose a point one side of the graph but not on the graph itself. Solve the inequality for that point, if it satisfies the inequality then that region having that point will be shaded. If that point does not satisfy the given inequality then that region won’t be shaded.

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.
