1-4.

Notice the familiar geometric shape.

Find the area of the negative region and combine
it with the positive area found in part (a).

A (f, 0 ≤ x ≤ 5) + A (f, 5 ≤ x ≤7)

A (f, 0 ≤ x ≤ 5) + A (f, 5 ≤ xk)

$[\text{area from part a}]+\frac{1}{2}(k-5)(-k+5)=\underline{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ }$
