Question

Describe how the graph of y=log (10 000x) is related to the graph of y=log x

Answer 1

Background: log (a . b) = log a + log b 
hence log(10000x) = log 10000 + log x but we know that log 10000 = 4
                               = 4 + log x 
therefore the graph of log(10000x) is just the graph of log x transposed by 4
