Evaluate this integral. I'm not sure how to evaluate integrals with absolute values.

SOVA2 [1]

Answer:

Step-by-step explanation:

The first step is to understand what the integrand looks like. (See the graph below.)

It is -1 for x < 0 and +1 for x > 0. Thus, the value of this integral is ...

$\int\limits^0_{-1} {-1} \, dx + \int\limits^2_0 {1} \, dx=-1+2=1$

_____

Essentially, you treat the absolute value as a piecewise linear function. This is the same way you treat an absolute value in any equation or inequality.

Here, this means you divide the integral into two parts: one where the integrand is -x/x, and one where it is +x/x.

Match each pair of polynomials to their sum.

<span>Answers:

(12x^2 + 3x + 6) + (-7x^2 – 4x – 2) = 5x^2 - x + 4

(2x2 – x) + (-x – 2x2 – 2) = -2x - 2

(x3 + x2 + 2) + (x2 – 2 – x3) = 2x^2

(x2 + x) + (x2 + 8x – 2) = 2x^2 + 9x - 2
