Learn how to solve definite integrals problems step by step online. Integrate the function 4-9y from -1 to 1. Expand the integral \int_{-1}^{1}\left(4-9y\right)dy into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int_{-1}^{1}4dy results in: 8. The integral \int_{-1}^{1}-9ydy results in: 0. Gather the results of all integrals.
