average rate of change = slope
Use slope formula. (Rise over Run)
[latex]m = \frac{y_2 - y_1}{x_2 - x_1}[/latex]
look at the 2 points where x=0 and x = 2, this interval covers the first 2 seconds.
f(0) = 50, f(2) = 100
[latex]m = \frac{100 -50}{2-0} = \frac{50}{2} = 25[/latex]
The avg rate of change is 25 units per second.
