Question

Use the graph below to answer this question:

Answer 1

The answer for this is C . 1

Answer 2

$\bf slope = m = \cfrac{rise}{run} \implies \cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby \begin{array}{llll} average~rate\\ of~change \end{array}\\\\ -------------------------------\\\\ \begin{array}{cllll} (\stackrel{x_1}{-3},\stackrel{y_1}{1})\\\\ (\stackrel{x_2}{1},\stackrel{y_2}{5}) \end{array}\begin{cases} x_1=-3\\ x_2=1 \end{cases}\implies \cfrac{f(1)-f(-3)}{1-(-3)}\implies \cfrac{5-1}{1+3}\implies 1$
