WebA quadratic function is a polynomial function of degree two. The graph of a quadratic function is a parabola. The general form of a quadratic function is f(x) = ax2 + bx + c where a, b, and c are real numbers and a ≠ 0. The standard form of a quadratic function is f(x) = a(x − h)2 + k where a ≠ 0.

WebBut they are essentially the same thing; f (x) is a function where if we input any non-restricted x value we will map out a "y" value. Thus "y = f (x)". One convenient use of "f (x)" is that we can use separate equations/functions and not confuse ourselves. e.g.: f (x) = 3x + 4. g (x) = (1/2)x - 2. If we used y, then we could get confused by ...
