Question

The graph below plots a function f(x): graph of line segment going through ordered pairs 0, 50 and 2,100 and extend beyond 2,100 If x represents time, the average rate of change of the function f(x) in the first two seconds is _______.

Answer 1

25 is the rate of change! This is correct trust me

Answer 2

The average rate of change will be equivalent to the slope of the line in the first two seconds. Thus:
Rate of change = (100 - 50) / (2 - 0)
Rate of change = 25 per second.
