The three methods of solving systems of equations are substitution, elimination, and graphing.

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. Example.

The two most common forms for writing the equation of a line are y=mx+b (slope-intercept form) and y?y1=m(x?x1) (point-slope form), where m is the slope of the line, and b is the y-intercept.

IfMoreDo you know how to write an equation. Using function notation let's take a look at an. Example. If the equation is already in a form like this one slope intercept form we can simply substitute Y.

Common Functions Reference Linear Function: f(x) = mx + b. Square Function: f(x) = x2 Cube Function: f(x) = x3 Square Root Function: f(x) = ?x. Absolute Value Function: f(x) = |x| Reciprocal Function. f(x) = 1/x.

A function will only have one or zero outputs for any input. If there is more than one output for a particular input, the equation does not define a function.
