Answer

(6.96,8)

Work Step by Step

In order to find the intersection, first create a well-labeled coordinate axis. Then, draw the line y=8, which will be a horizontal line through the point (0,8). Next, draw the exponential function. This function should start at a small value when x is negative and increase slowly, passing through the point (1,0). Be sure to draw the function so that as x increases, the slope increases as well. Then, find where the two graphs intersect. (To obtain a precise value, use a graphing calculator or an online graphing program.)
