Answer:
[tex]-\dfrac{5}{4}[/tex]
Step-by-step explanation:
average rate of change of function f(x) between x = a and x = b
[tex] \dfrac{f(b) - f(a)}{b - a} [/tex]
Here, a = 0; f(a) = f(0) = -5; b = 4; f(b) = f(4) = -10
[tex] \dfrac{f(b) - f(a)}{b - a} [/tex]
[tex]= \dfrac{-10 - (-5)}{4 - 0}[/tex]
[tex]= \dfrac{-5}{4}[/tex]
[tex]= -\dfrac{5}{4}[/tex]
