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 three seconds is

If x represents time, the average rate of change of the function f(x) in the first three seconds is  40.

We know that the average rate of change which is also know as a slope of a function from x=a to x=b is calculated by the formula:

Here we are asked to find the average rate of change between x=0 to x=3 ( i.e. in the first three seconds)

It is calculated as follows:

the answer is c)8

step-by-step explanaction:

the answer is option a you would get more money.it would be $250.

step-by-step explanation:

for option b 200/2=100=50% 100/2=50=25% 50/5=10=5% it would be $220
