Find the area of the region under the graph of f on [a, b].<br> f(x) = x2 − 8x + 17; [−1, 2]

Harman [31]

Answer:

The area is 42 area units.

Step-by-step explanation:

The area of a function f(x) on an interval [a,b] is given by:

$A = \int\limits^a_b {f(x)} \, dx$

Applying to this question:

$A = \int\limits^-1_2 {x^2 - 8x + 17} \, dx$

Then

$F(x) = \frac{x^{3}}{3} - 4x^{2} + 17x$

$A = F(2) - F(-1)$

$F(2) = frac{2^{3}}{3} - 4*2^{2} + 17*2 = \frac{8}{3} + 18 = \frac{8 + 3*18}{3} = \frac{62}[3}$

$F(-1) = frac{(-1)^{3}}{3} - 4*(-1)^{2} + 17*(-1) = -\frac{1}{3} - 21 = \frac{-1 - 21*3}{3} = -\frac{64}[3}$

$A = F(2) - F(-1) = \frac{62}[3} - (-\frac{64}[3}) = \frac{62+64}{3} = 42$

The area is 42 area units.

Step-by-step explanation:

Dear Gentleman Scholar —

Recently, I nearly reduced a woman to tears when she gently proffered her hand to me at a work conference and I vigorously squeezed it and yanked her around like the Incredible Hulk shaking hands with Raggedy Ann. There was much metacarpal cracking and muted whimpering. Having (I thought) learned my lesson, later at the same event when another women extended her hand, I very gently held hers and then released. There were no injuries this time, but she glared at me as if I had just handed her a dead fish. How does a gentleman shake hands with a lady? Am I supposed to shake it, caress it, kiss it, just hold it for a moment? What gives?

Yours,
