integral of-2e^y

\int - 2 e^{y} d y

- 2 e^{y} + C

Solution steps

\int - 2 e^{y} d y

Take the constant out:

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

= - 2 \cdot \int e^{y} d y

Use the common integral:

\int e^{y} d y = e^{y}

= - 2 e^{y}

Add a constant to the solution

= - 2 e^{y} + C

\int e^{2 x^{2} + l n (x)} d x

\int r^{- 1} d r

\int 7 x^{2} + 8 x^{- 2} d x

\int 5 x (2 x^{2} + 1)^{- 3} d x

\int \frac{x + 3}{2 x + 1} d x
