Y+log(lower case 3) x How do I find the domain and range

Question

y=log3x  Use a graphing calculator to graph each log function.  Give the coordinates of two points through withic the graph passes, then state the vertical asymtote of the graph.  Lastly, identify the domain and range of each function.  Scketch the graph

Answer 1

y=log₃(x) is the same as x=3^y.

Coordinates of two points: (1,0) and (3,1). VA is x=0 (y-axis).
