integral from-3 to 3 of 2x^2

\int_{- 3}^{3} 2 x^{2} d x

36

Solution steps

\int_{- 3}^{3} 2 x^{2} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int_{- 3}^{3} x^{2} d x

Apply the Power Rule

= 2 [\frac{x ^{3}}{3}]_{- 3}^{3}

Compute the boundaries:

18

= 2 \cdot 18

Simplify

= 36
