Answer

$(.19,0) $ and $(-3.62, 0)$

Work Step by Step

In order to find the intersection, first create a well-labeled coordinate axis. Then, draw the line y=0, which will be a horizontal line through the point (0,0). Next, draw the logarithmic function. This is difficult using only the information you know now, so you may want a graphing calculator to assist you. Doing this, find the two spots where the graphs intersect.
