Question 1044858: Hello!
My question is: find the domain of the function f(x)= (x^2-16)/7
I have tried to research how to figure this out, but I am unclear of the steps to find a solution. All I know is that x apparently can be any rational number so it is infinite? I am unclear of the steps to figure this out. Thank you so much!

Answer by MathLover1(20850) (Show Source): You can put this solution on YOUR website!
recall:
All the values that go a function are called the .
The values are called the .
Now, what comes out (the Range) depends on what we put in (the Domain).
→ →
the domain of the function is (all real numbers); no matter what value you take for you will always get value for , means function is defined

one more example if we have in denominator:
The domain of is all the Real Numbers , except
is at because would be dividing by zero
