Transformations of Exponential Functions - Introduction

In 1a) I misspoke and said "(0,0) is moved down to the origin" when I meant "(0,1) is moved down to the origin".

In the second problem I could have indicated s(x) = -u(x) in addition to s(x) = r(-x)

Transformations: Domains and Ranges

For h(x) =3^(x-2) + 1 in Step 2 I said "x is replaced by x - 1" when I meant "x is replaced by x - 2".

Time ran out before I could give the summary for y = 3 - 2^(x-1) -
domain: (-infinity, infinity); range (-infinity,3) ; asymptote: y = 3
