So I have a question regarding advanced functions, logarithm stuff.
here is the question:
Beginning with the function f(x) = log[base(a)]x ,state what transformations were used on this to obtain the functions given below:
a) p(x) = (5/8) log [base(a)]x
b) r(x) = log[base(a)](5x)
c) t(x) = 2log[base(a)]2z
My answers are the following, need them checked please.
a) vertical compression (5/8)
reflect across the vertical axis (not sure how to explain this transformation, do I say it before or after the shift?)
b) vertically stretched by 2
horiz. stretch by 2 as well
Thx

crap, i screwed up writing my answers. Ignore them please.
