If x represents the time the average rate of change of function in the first two seconds is

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