absolute value function a function of the form f(x)=|mx +b|+c, where m 0
dependent variable because the value of y depends on the value of x,y
direct variation a linear function defined by an equation of the form y= kx where k=0
domain a relation is the set of all inputs ,or x-coordinates of the ordered pairs
functions a relation in which each element of the domain is paired with exactly one element in the range
function notation f(x) as "f of x "or "a function f of x"
independent variable if a function is defined by an equation using the variables x and y, where x represents input values , then x is the independent variable
linear equation a linear equation in two variables is an equation that can be written in the form ax+by =c
linear function a function whose graph is a line is a linear function. you can represent a linear function with a linear equation
