1-84.

Examine the graph of at right.

Calculate the area of the shaded region using geometry. (Recall that area below the

-axis is considered negative.)Find the area of each triangle separately. Recall that the area below the

-axis is negative. Add the negative and the positive regions together. What is the value of

if the area under the curve foris ? How did you obtain your solution? Simplify, and solve for

.
