What are the basics of quadratic formula and function, how you can solve quadratic equations. A calculator for…
f(x)=y

$\lim_{x \to \infty} \exp(-x) = 0$

$f(n) = n^5 + 4n^2 + 2 |_{n=17} \,$

Graph a Quadratic Formula

Use this tool to graph or explore the graph of a quadratic function. Just enter its parameters and the interval, for which the graph to be calculated.

For example if you want to see the quadratic graph of the equation: ax^2 + bx + c = 0 , for x= 5 , you need to fill the forms as shown. Once your graph is drawn, you can change the input data to see what its effect would be on the graph. If you need a quicker quadratic grapher, you can try our quadratic equation explorer. All the changes of the parameters will be calculated immediately there, but it’s a little bit limited…

#### The Quadratic Formula

If we have an equation like:, the following formulas apply to it:
