Find the average rate $of$ change for the given function.

$f(x)=x^2+11x$ between $x=0$ and $x=4$

What expression can $be$ used $to$ find the average rate $of$ change $of$ the function $f(x)$ over $0,4?$

$A.\underset{x0}{lim}\frac{f(4)-f(0)}{4-0}$

$B.\underset{h0}{lim}\frac{f(0+h)-f(0)}{h}$

$C.\frac{f(4)+f(0)}{4+0}$

$D.\frac{f(4)-f(0)}{4-0}$

The average rate $of$ change $off(x)$ over $0,4is$
