A quadratic function is any function that can be written in the form y = ax^{2} + bx + c, where *a*, *b*, and *c* are real numbers and *a* â‰ *0*.
It is a really important function to understand, as you'll see it over and over
in math and beyond. In fact, it's so important that today's free Algebra 1
video has a total of 5 lectures on it! Professor Burger covers everything from
what makes the quadratic function a quadratic to what the graphs of quadratics
look like. Big hint: they're parabolas! I absolutely love graphing equations
and today's video has several lectures covering just that. By the time you
finish with all the lectures, you'll be able to just look at an equation and
tell a lot about what the graph will look like.
