integral from 0 to 4 of f(x)

\int_{0}^{4} f (x) d x

f \cdot 8

Solution steps

\int_{0}^{4} f x d x

Take the constant out:

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

= f \cdot \int_{0}^{4} x d x

Apply the Power Rule

= f [\frac{x ^{2}}{2}]_{0}^{4}

Compute the boundaries:

8

= f \cdot 8
