Note: You can't go through algebra without seeing quadratic functions. The graphs of quadratic functions are parabolas; they tend to look like a smile or a frown.

Yes and yes! This shape that the swing outlines is an example of what a quadratic equation gives you when you graph it. In math, we define a quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic is y = ax ^2 + bx + c, where a, b, and c are numbers and a cannot be 0. Examples of quadratic equations include all of these: 1  y = x ^2 + 3 x + 1.
