A. Explain why the point (100,2) is on the graph.

Crazy boy [7]

Answer:

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

by definition $log_{a} b = c$ then $a^{c} = b$

in this problem you have $log_{10} 100$

thus what x solves this ? $10^{x} = 100$ the answer is $10^{2}$

thus (100,2)

B) the x intercept is when y = 0

$10^{0} = 1$

x intercept at (1,0)

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