Evaluating a function means finding f (x) at some specific value of x. So, evaluating a function at a constant or a variable involves substituting the constant or the variable into the expression of the function and calculate its value. Example: Given f (x) = - x2 + 4x - 1 find, a) f (-1) and b) f (x + 2).
