Quadratic Function Calculator
The word "Quadratic" is derived from the word "Quad" which means square. In other words, a quadratic equation is an “equation of degree 2”.

How to Find Quadratic Function?
An equation of the form y = f(x) = ax2 + bx + c, where a≠0 is called a quadratic function and a, b, c are coefficients of the quadratic function. When a quadratic equation is plotted in a graph, the graph obtained is a parabola in shape
Let's see an example to understand briefly.
Compute the graph for y = f(x) = 5x2 + 6x + 3
For x = 0, y = 5(0) + 6(0) + 3 ⇒ y = 3
For x = 1, y = 5(1) + 6(1) + 3 ⇒ y = 14
For x = 2, y = 5(4) + 6(2) + 3 ⇒ y = 35
Similarly for x = 3, x = 4, and .....
Plot these points in the graph
Similarly, you can use the calculator to compute the given quadratic functions:
- y = f(x) = 3x2 - 5x + 5
- y = f(x) = 6x2 + 3x - 11
