By the end of this module you will be expected to have learned the following formulae:






![{\displaystyle x^{\frac {a}{b}}={\sqrt[{b}]{x^{a}}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/c334c9763de15e6e7f7cd9c6f0edf4905026a548)





If f(x) is in the form
- -b is the axis of symmetry
- c is the maximum or minimum y value
Axis of Symmetry =
becomes
- The solutions of the quadratic
are: 
- The discriminant of the quadratic
is 



The equation of a line passing through the point
and having a slope m is
.
Lines are perpendicular if
, where (h,k) is the center and r is the radius.
- Derivative of a constant function:
- The Power Rule:
- The Constant Multiple Rule:
- The Sum Rule:
- The Difference Rule:
- If
and
, then c is a local maximum point of f(x). The graph of f(x) will be concave down on the interval.
- If
and
, then c is a local minimum point of f(x). The graph of f(x) will be concave up on the interval.
- If
and
and
, then c is a local inflection point of f(x).
