What is the difference in solving functions when giving the following information: f(x)=2 and f(2)

vfiekz [6]

*Remember that y and f(x) are the same.

With f(2), you are solving for the output (y), given that the input (x) is equal to 2.

With f(x) = 2, you are solving for the input (x), given that the output (y) is equal to 2.
