Examine the graph of the function f(x) = 0.5x − 2 below. Homework Help ✎
Find the area of the shaded region using geometry. (Recall that the area below the x-axis is considered negative.)
Find k if A(f, 0 ≤ x ≤ k) = l0. How did you find your solution?
Find the area of each triangle separately. Recall that the area belowthe x-axis is negative. Add the negative and the positive regions together.
[Area of triangle A] + [Area of triangle B]
[Area of triangle A] + [Area of triangle B] = 10
Simplify, and solve for k.
