Example 1 Graph the logarithmic function f(x) = log 2 x and state range and domain of the function Solution Obviously, a logarithmic function must have the domain and range of (0, infinity) and (−infinity, infinity) Since the function f(x) = log 2 x is greater than 1, we will increase our curve from left to right, a shown below Horizontal Movement If you want to find out if the graph will move either left or right, consider y=f (x±c) If c is negative, the graph moves to the right If c is positive, the graph moves to the left As an example, if I have f (x)= (x3) 3,A General Note Graphical Interpretation of a Linear Function In the equation latexf\left(x\right)=mxb/latex b is the yintercept of the graph and indicates the point (0, b) at which the graph crosses the yaxis;
