Explanation of Solution

Given information:

A function is f(x)=3x2;x=2,x=2+h

Formula used :

The average rate of change of function f(x2)f(x1)x2x1 .

Calculation : The function is f(x)=3x2 for x=2,x=2+h

Put the values of x1 and x2 into the formula

  f(2+h)f(2)(2+h)(2)[3(2+h)2]3(2)2h3(4+4h+h2)3(4)h12+12h+3h212h12h+3h2hh(12+3h)h12+3h
