# Find the derivatives of the functions in Problems 1-14. y = 6 − 8 x + 2 x 2

To determine

To calculate: The derivative of the function y=68x+2x2.

Explanation

Given Information:

The provided function is y=68x+2x2.

Formula Used:

Sum rule for function f(x)=u(x)+v(x), where u and v are differentiable functions of x, then,

f(x)=u(x)+v(x)

Difference rule for function f(x)=u(x)v(x), where u and v are differentiable functions of x, then,

f(x)=u(x)v(x)

Power of x rule for a real number n is such that, if f(x)=xn then f(x)=nxn1.

Coefficient rule for a constant c is such that, if f(x)=cu(x), where u(x) is a differentiable function of x, then f(x)=cu(x).

Constant function rule for a constant c is such that, if f(x)=c then f(x)=0
