It means f(x)=x2+2f(x) = x^2 + 2f(x)=x2+2 for all xxx.
The set of xxx values allowed to be input in a function.
The set of yyy values that f(x)f(x)f(x) can take for a domain.
The domain is {x:x>3}\{x: x > 3\}{x:x>3}.
A domain where the function is undefined for some xxx values.
Range is {y:y≥e2}\{y: y \geq e^2\}{y:y≥e2}.
Range is (−∞,2](-\infty, 2](−∞,2] as xxx goes from 000 to ∞\infty∞.
Multiple xxx values map to a single yyy value.
One xxx value gives multiple yyy values, no inverse exists.
