Evaluate the function at the indicated values if possible. if an indicated value is not in the domain, say so.
f left parenthesis x right parenthesis equals startfraction x plus 7 over x squared minus 9 endfraction
; f left parenthesis negative 7 right parenthesis, f left parenthesis 2 right parenthesis, f left parenthesis 3 right parenthesis

f(-7)=0.

f(2)=-9/5.

f(3) doesn't exist because 3 isn't in the domain of the function.

Step-by-step explanation:

is the given function.

We are asked to find:

.

f(-7) means to replace x in the expression called f with -7:

Evaluate at

So f(-7)=0.

f(2) means to replace x in the expression called f with 2:

Evaluate at

So f(2)=-9/5

f(3) means to replace x in the expression called f with 3:

Evaluate at

Division by 0 is not allowed so 3 is not in the domain of our function.

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.
