Thread: Logarithmic Help

First of all, sorry if this is in the wrong category, first time here. If it is, please direct to where I need to be. Thank you.

A couple of questions I have, the first of all is"

Sketch the graph y = 3^ax + b, where a>0, b>0. Label and axial intercepts in coordinate form and equation of the asymptote.

I haven't done this kind of stuff in a while and I've drawn a blank, if you could show me the working out, that'd be cool. Thank you in advance.

Another question I has was:

Consider the function with the rule y = log₁₀ (2x-3).
I need to sketch the graph with the asymptote and the coordinates of any axes intercepts.
I also need to state the domain and range.

Any help would be greatly appreciated. Thank you in advance.
