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.

its kind of blurry. can you put a clearer pic?
