Drawing an Integration Graph

Example: To determine the integration result for the quadratic function y =–x

+4x within the range of x =0to4.

At the same time, draw the function graph for the definite integral derived from

the quadratic function and verify the results.

Use View Window to configure the graph screen coordinate values.
