In Exercises 13-28, calculate d y d x . Simplify your answer. [HINT: See Example 1 and 2.] y = 3 x 2 ( 2 x + 1 )

To determine

To calculate: The derivative of function y=3x2(2x+1).

Explanation

Given Information:

The function is y=3x2(2x+1).

Formula used:

Product rule of derivative of differentiable functions, f(x) and g(x) is,

ddx[f(x)g(x)]=f'(x)g(x)+f(x)g'(x)

Sum rule of derivative is ddx[f(x)+g(x)]=ddxf(x)+ddxg(x).

Constant multiple rule of derivative of function y is ddx(cx)=cddx(x) where c is constant.

Derivative of function y=xn using power rule is ddx(xn)=nxn1.

Derivative of a constant is 0.

Calculation:

Consider the function, y=3x2(2x+1)
