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.
