Hello, I need help with this problem. Thanks in advance.

Sketch the graph of the integrand function below and study it to find a simple way to evaluatethe integral . Verify your answer by calculating the integral using known functions for theintegrand in place of the absolute function over appropriate sub- intervals between theintegration limits O and 4 .Solx = 21 - 1 dx
