integral from-2 to 9 of f(x)

\int_{- 2}^{9} f (x) d x

\frac{77 f}{2}

Solution steps

\int_{- 2}^{9} 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_{- 2}^{9} x d x

Apply the Power Rule

: [\frac{x ^{2}}{2}]_{- 2}^{9}

= f [\frac{x ^{2}}{2}]_{- 2}^{9}

Compute the boundaries:

\frac{77}{2}

= f \frac{77}{2}

Simplify

= \frac{77 f}{2}

\frac{\partial}{\partial y} (2 x y^{3} + 3)

\frac{4}{x + 2}

\int \frac{4 t ^{3} - 3 t ^{2} + 4 t}{t ^{2} + 1} d t

\int \frac{4 x}{( x ^{2} + 4 ) ^{2}} d x

\frac{\partial}{\partial x} (x e^{y} + y e^{x})
