It's confusing to know the right order of what goes first. I'm having a hard time understanding if the function's value is -5 at -25 or -25 at -5. I don't understand the difference.

To AngleRoman, Due to my training in what is call the Texas-Method, the wording of definitions is really important.
In the list given above, I am prepared to argue that only two of those are a hundred percent correct.
One other is loosely equivalent to those two, but lacks precision.
Three are just flat-out wrong. I tell you this in part to indicate that you may not get a correct answer.

This is just a convention - no particular reason behind it. We write (x,y) - first the independent variable (x) then the dependent variable [y or f(x)].

So it is y = -25 {function's value [f(x)]} at x = -5

Thank you Subhotosh and Pka for your help. I got the right answer from following the information you gave. Thanks so much

Function notation (click link):

G(input) = output

G(x) = y

G(-5) = -25

?

x comes before y, just like in the alphabet
