Question

If you were to solve a function and you are subtracting from x do you subtract or add

G(2)-2=2squared-2
what do you do with the minus 2 at the beginning?

Answer 1

well what you do is you leave it since g(x) is a function
iff you don't know what g(x) is, then treat g(x) as an unknown, or ?

?-2=2^2-2
add 2 to both sides
?=2^2
?=4
g(2)=4
