12-17.

Approximate the area under the curve $y = x^{2} − 8$ over the interval $1.5 ≤ x ≤ 4$ using $10$ right endpoint rectangles.

Determine the width of each rectangle.
$\frac{4-1.5}{10}$

Write an equation for the endpoints.
$x_0= 1.5, x_1 = ?, x_2=?, ...x_n =$

area = $\displaystyle \sum _ { n = 1 } ^ { 10 } \frac{4-1.5}{10}f(x_n)$
