1. The function y  2 x is transformed to a new function with the rule y  2x 1  2 .
a) List the transformations that have been applied to the original function.
b) Sketch the graph of the transformed function. In your sketch mark all significant
features including the location of any axes intercepts and asymptotes.
c) State the domain and range of y  2x 1  2 .

4. a) Evaluate log 32 2 .
b) Express log x 9  2 as an exponential equation and hence find the value of x.
c) If 3 + log2 (4x) = log2 (y), find y in terms of x.
