document.write( "Question 763782: Match a graph to a given logarithmic function. I understand how to get logarithms back and forth, but then I'm asked to identify them on a graph. I also understand how to graph a given number by using -2, -1, 0, 1, 2 and then switching them, but as an equation such as: y=-log3(-X) on a graph, I don't see it. I tried using the numbers above but the test results gave a similar but different result. Please help, thank you.

You can put this solution on YOUR website!
TWO Key ideas: Learn the shape of the basic exponential function; define logarithm function as the inverse of the exponential function AND learn the basic shape of the logarithm function graph. \r

\n" ); document.write( "\n" ); document.write( "If you reflect the exponential function graph through the line y=x, you get the logarithm function graph, and x and y values are exchanged, or switched.
\n" ); document.write( "A point, (a,b) on the exponential function graph will become the point, (b,a) on the logarithm graph. \n" ); document.write( "
