Use the graph below to answer this question:
 (graph of line going through negative 3, 1 and 1, 5) 

 Find the average rate of change for the given function from x = −3 to x = 1.

A: −1
B: −2
C: 1
D:  2

Respuesta :

[tex] \bf slope = m = \cfrac{rise}{run} \implies
\cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby
\begin{array}{llll}
average~rate\\
of~change
\end{array}\\\\
-------------------------------\\\\
\begin{array}{cllll}
(\stackrel{x_1}{-3},\stackrel{y_1}{1})\\\\
(\stackrel{x_2}{1},\stackrel{y_2}{5})
\end{array}\begin{cases}
x_1=-3\\
x_2=1
\end{cases}\implies \cfrac{f(1)-f(-3)}{1-(-3)}\implies \cfrac{5-1}{1+3}\implies 1 [/tex]
The answer for this is C . 1
