What is the average Rate of Change for the function f(x) = x ^ 2 + 7x - 4 over the interval [0, 2]

The average rate of change of function f over the interval [0, 2] is 9.

Step-by-step explanation:

To find the average rate of change of a function over an interval, we evaluate the function at the endpoints of the interval and find the slope between them.

We are given the function:

And we want to find its average rate of change over the interval [0, 2].

So, evaluate the function at the endpoints:

And find the slope between them:

So, the average rate of change of function f over the interval [0, 2] is 9.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
