Red kangaroos can reach speeds up to 50 feet her

The change in y-values from point A to B = 50

The change in x-values from point A to B = 1

The rate of change of the given function = 50 feet per second

Step-by-step explanation:

From the given graph , the coordinates of point A=(3,150) and B=(4,200)

Now, the change in y-values from point A to B =

The change in x-values from point A to B =

The rate of change of function is given by :-

Hence, the rate of change of the given function = 50 feet per second

y=sec x is the correct answer
