## Answer

## Step by step solution

Problem

The integral of a sum of two or more functions is equal to the sum of their integrals

Taking the constant out of the integral

Taking the constant out of the integral

Apply the power rule for integration, $\displaystyle\int x^n dx=\frac{x^{n+1}}{n+1}$, where $n$ represents a constant function

Simplify the fraction

Applying the power rule for integration, $\displaystyle\int x^n dx=\frac{x^{n+1}}{n+1}$, where $n$ represents a constant function

Multiply $\frac{1}{2}$ times $4$

Add the constant of integration
