We have just recently been doing transformations of sin and cos graphs, but we must find out transformations of logarithm graphs.(adsbygoogle = window.adsbygoogle || []).push({});

A typical log function could be log (x).

What i want to know is, when you change the base, what would happen to the graph, when you put a number out the front, what would happen to the graph, adding or subtracting a number in the brackets [ log (x +2) ] or even adding or subracting numbers at the end.

Any help on what these situations would do to these graphs would be greatly appreciated, also, i have a situation where a log function cuts the y axis at around 2.1, and the x axis at around 1.7. We gotta use transformations to obtain the graph.

So if any help can be provided to help make a log function that describes the situation above, or with transformations of logs in general, it would be much helpful. Thanks
