Solve math equation
Math is a way of solving problems by using numbers and equations.
f (x) = x 2 Quadratic functions follow the standard form: f (x) = ax 2 + bx + c If ax2 is not present, the function will be linear and not quadratic. Quadratic functions make a parabolic U-shape on a graph. If a is negative, the parabola is flipped
