2.2 - Solving Equations Graphically
The x-intercept is the point where the graph of an equation crosses the x-axis. The xintercept can be found by substituting y=0 into the equation and solving for x. The xinterc
2.4 - Solving Equations Algebraically
A quadratic equation is an equation that can be written as Ax2 + Bx + C = 0 where A0.
This form is called the standard form.
There are four ways to solve a quadratic equation.

1.7 - Inverse Functions
The inverse of the function f is denoted by f -1 (if your browser doesn't support
superscripts, that is looks like f with an exponent of -1) and is pronounced "f inverse".
Although the inverse of a func

Arithmetic Combinations of Functions
The sum, difference, product, or quotient of functions can be found easily.
(f + g)(x) = f(x) + g(x)
(f - g)(x) = f(x) - g(x)
(f g)(x) = f(x) g
