Final answer to the problem
Step-by-step Solution
Learn how to solve integrals of polynomial functions problems step by step online. Find the integral int(4x^3)dx. The integral of a function times a constant (4) is equal to the constant times the integral of the function. Apply the power rule for integration, \displaystyle\int x^n dx=\frac{x^{n+1}}{n+1}, where n represents a number or constant function, such as 3. Simplify the fraction 4\left(\frac{x^{4}}{4}\right). As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration C.
