sketch graphs of $y=af(k(x-d))+c$ by applying one or more transformations to the graph of $f(x)=a^x$ $(a>0,a\ne 1)$, and state the domain and range of the transformed functions Sample problem: Transform the graph of $f(x)=3^x$ to sketch $g(x)=3^{-(x+1)}-2$, and state the domain and range of each function.
