Q:
# Select the correct function.Select the function with an average rate of change of -6 over the interval [2, 4].

Accepted Solution

A:

Check the picture below.so let's use those two points the line passes through to get its slope.[tex]\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-12}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-12-0}{4-2}\implies \cfrac{-12}{2}\implies -6[/tex]
