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)](5-x)

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
