Question

Find the equations:

 

f+g =

 

f-g =

 

f×g =

 

f÷g =

 

 

 Enter the answers in fully simplified and expanded form...

 

I was able to find all the DOMAINS except the last one f÷g ?

Thank You :-)....

 

 

Answer 1

Think about what values of x would make f÷g (f/g) an invalid function. Division by a number is a valid operation provided the number isn't zero. So we want to ask ourselves what values of x make it so f/g is division by zero and leave them out.
