Because you cannot "just simplify" unless you specifically exclude ##x=2## at which point, as you have discovered, the function is... -

The two functions are identical except at the point (2, 4). The graph of ##f(x) = \frac{x^2 - 4}{x - 2}## can be thought of as a...

gen x posted the thread High School Why simplifying this function generates different outputs for same input? in General Math.This function ##f(x) = \frac{x^2 - 4}{x - 2}## when simplify become ##f(x) = x + 2## . If I enter ##x=2## in the first expression I...
