Explanation of Solution

Given information: consider the function f(x)=38x2x2

Calculation:

Take any values of x and then make a table of values.

  xf(x)=38x2x2238(2)2(2)2=11138(2)2(1)2=9038(2)2(2)2=3138(2)2(2)2=7238(2)2(2)2=21

Then, plot the points given by the table and join them by a smooth curve to obtain the graph f(x)=38x2x2 as shown below:
