A link to practice
factoring 2nd degree monic polynomials with integer coefficents.
The format changed for later ones.
One for solving linear inequalities - including absolute value inequalities.
One for graphing parabolas.
One for the basic ideas of functions.
One for simplifying rational expressions with integer exponents.
This graphs a function and lets you vary three parameters: three parameter graph
Note: In the three parameter graph, multiplication must be explicit.
For example, it will not recognize ax as a*x.
