# FNGR 2 | Lesson 2 | Explore (Graphing Quadratic Functions)

Explore the sliders for $$a$$, $$b$$, and $$c$$ to see how changing these values impacts the graph of the parabola.

Graphing Quadratic Functions | Desmos

Explore this graph of the quadratic parent function. What can be said about the vertex? What about the orientation (does it open up or down?)

$$y=x^2$$

A quadratic function can be written in standard form, as shown in the “slider” function in green below.

$$y=ax^2 + bx + c$$

For the Explore the sliders for $$a$$, $$b$$, and $$c$$ to see how changing these values impacts the graph of the parabola.

Note that $$a = 0$$ to begin with.
