By definition we have that the average rate of change of the function is given by:
[tex]AVR = \frac{f(x2) - f(x1)}{x2 - x1} [/tex]
Substituting values we have:
[tex]AVR = \frac{100 - 50}{2 - 0} [/tex]
Rewriting we have:
[tex]AVR = \frac{50}{2} [/tex]
[tex]AVR = 25 [/tex]
Answer:
If x represents time, the average rate of change of the function f(x) in the first two seconds is 25.
[tex]AVR = \frac{f(x2) - f(x1)}{x2 - x1} [/tex]

[tex]AVR = \frac{100 - 50}{2 - 0} [/tex]
Rewriting we have:
