A. Explain why the point (100,2) is on the graph. B. What is the x-intercept of the graph? Explain how you know.
49
C. When will the graph meet the line y = 5? Explain how you know.

the log function is the "inverse" function of an exponential function

by definition    then

in this problem you have

thus what x solves this ?    the answer is

thus (100,2)

B) the x intercept is when y = 0

   x intercept at (1,0)

C) at 100, the curve will hit y = 5000
