Hey there,
Your question states:
The domain for f(x) and g(x) is the set of all real numbers.
Let f(x) = 3x + 5 and g(x) = x2.
Find g(x) − f(x).
So, if [tex]\boxed{\boxed{f(x) = 3x + 5 \ and \ g(x) = x2.}}[/tex], and what we are trying to figure out is [tex]g(x) - f(x)[/tex], would would have ti find an expression that would by means fit with f(x) = 3x + 5 and g(x) = x2.
I would say that the answer would be x2 − 3x − 5.
By plugging in the f(x) = 3x + 5 and g(x) = x2, I believe that this would make more sense.
Hope this helps.
