By the injectivity assumption, we have. f(xy + x + 2xf(y)) = f(xy) + f(x) = f(xy + x + 2f(x2y)). Stripping f off both sides of the identity above, we find that. f(x2y) = xf(y). So it follows that f(x) = f(1)√x, and plugging this back to the functional equation shows that f(1) = 1. Therefore f(x) = √x. ////.We will see later that points with ∇f = ~0 are candidates for local maxima or minima of f.

The Function which squares a number and adds on a 3, can be written as f (x) = x2+ 5. The same notion may also be used to show how a function affects particular values. Example. f (4) = 4 2 + 5 =21, f (-10) = (-10) 2 +5 = 105 or alternatively f: x → x2 + 5. The phrase "y is a function of x" means that the value of y depends upon the value of ... function f(x,y) with fx = cos(x + y) and fy = ln(x + y)?.

By the injectivity assumption, we have. f(xy + x + 2xf(y)) = f(xy) + f(x) = f(xy + x + 2f(x2y)). Stripping f off both sides of the identity above, we find that. f(x2y) = xf(y).
