H(x) = x3 - 64x2. Determine the average rate of change of the function between x = -2 and x = 0
Marysya12 [62]
\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
\textit{average rate}\\
\textit{ of change}
\end{array}
\\\\\\
H(x)=x^3-64x^2\quad 
\begin{cases}
x_1=-2\\
x_2=0
\end{cases}\implies \cfrac{H(x_2)-H(x_1)}{x_2-x_1}
