integral from-infinity to 0 of e^{-|4x|}

\int_{- \infty}^{0} e^{- ∣ 4 x ∣} d x

\frac{1}{4}

Decimal Notation

0.25

Solution steps

\int_{- \infty}^{0} e^{- ∣ 4 x ∣} d x

Eliminate Absolutes

= \int_{- \infty}^{0} e^{- (- 4 x)} d x

Compute the indefinite integral:

\int e^{- (- 4 x)} d x = \frac{1}{4} e^{4 x} + C

Compute the boundaries:

\int_{- \infty}^{0} e^{- (- 4 x)} d x = \frac{1}{4} - 0

= \frac{1}{4} - 0

Simplify

= \frac{1}{4}

\int_{- 1}^{2} (4 x + 2) d x

\int_{- 2}^{2} \frac{x ^{2}}{1 + x ^{3}} d x

\int_{0}^{π} 1 + cos (x) d x

\int_{0}^{1} k (2 - x) d x

\int_{1}^{\infty} x^{n} d x
