Question

[ Please help ] The graph below plots a function f(x).

If x represents time, the average rate of change of the function f(x) in the first two seconds is _______.

Answer 1

25 (units of distance/units of time)

The first two seconds are determined between points (0,50) and (2,100). Given these points, finding the slope between them gives you the average rate of change:


`(Δy)/(Δx) = ((100 - 50))/((2 - 0)) = (50)/(2) = 25`
