Determine the domain of the function. f as a function of x is equal x divided by quantity x minus 9. all real numbers except - 9 all real numbers all real numbers except 9 x ≥ 0

The function is not defined when the denominator (x-9) is zero. The denominator will be zero when x=9, so that value must be excluded from the domain.

The domain is ...

... All real numbers except 9

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.
