$-\int e^xdx$
Learn how to solve definite integrals problems step by step online. Integrate the function -e^x from -infinity to 1. The integral of a function times a constant (-1) is equal to the constant times the integral of the function. The integral of the exponential function is given by the following formula \displaystyle \int a^xdx=\frac{a^x}{\ln(a)}, where a > 0 and a \neq 1. Add the initial limits of integration. Replace the integral's limit by a finite value.
Final Answer
$-e$
