Select the correct answer.
Find the inverse of function f.
95 + 7

D

Step-by-step explanation:

1. Make it into a y = x equation

       y = 9x +7

2. change x to y and y to x

       x = 9y + 7

3. Isolate y ( if not possible, use implicit differentiation but here you can)

      x-7 = 9y

      1/9x-7/9 = y

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
