22 x 85 = (20+2)*85= 20*85+ 2*85 = 1700 + 170 = 1870
Answer:
the coordinates of B is (-5,7)
The amount after 7 years is given by:

The answer is: $20,948.15
We have been given the function

We have to find the value of f(3). In order to find the same, substitute x=3 in the given function.

Now, we simplify this step by step.
First of all
. Thus, we have

Now, we can easily simplify it by PEMDAS


Therefore, the value of f(3) is 98.
