The equation in the form y=ax2+bx+c is called quadratic function.

A quadratic function has degree 2.

Example:

1. Find a, b, and c for the quadratic function

Solution : First write the standard form y=ax2+bx+c

Now find a, b, c by comparing both equations.

Therefore we have a=1, b=3, and c=5

Note: if a function is not in a standard form, you can
reorder the terms . First write the x2 term, then x term and
write the constant term last .
