Answer:

b) - 10

Step-by-step explanation:

<h3>Average rate of change:</h3>

To find the average rate of change, we have divide the change in y of f(x) , by the change in x(input).

   \sf \boxed{\text{\bf Average rate of change = $\dfrac{f(b)-f(a)}{b-a}$}}

 a = 4 ; f(a) = -17

b = 6 ;   f(b) = -37

     \sf Average \ rate \ of \ change = \dfrac{-37-[-17]}{6-4}

                                         \sf =\dfrac{-37+17}{2}\\\\=\dfrac{-20}{2}\\\\=-10
