OA. 8B. -8X0123C. 4OD. -4456y-125What is the average rate of change for this quadratic function for the intervalfrom x = 1 tx= 3?-10-17-26-37

Answer 1

- The formula for finding the average rate of change of a function over an interval [a, b] is:

`\Delta m=(f(b)-f(a))/(b-a)`

- Thus, we have that

`\begin{gathered} a=1,b=3 \\ f(a)=-2,f(b)=-10 \\ \\ \Delta m=(-10-(-2))/(3-1) \\ \\ \Delta m=(-8)/(2) \\ \\ \Delta m=-4 \end{gathered}`

Final Answer

The rate of change of the function is -4 (OPTION D)
