b) shifting two units to the right.
c) reflecting about the x axis.

Find the domain of the functions:
b) f(x) = 1/(1-e^x)
d) g(t) = SQRT(1-2^t)
19) Suppose the graphs of f(x)=x^2 and g(x)=2^x are drawn on a coordinate grid where the unit of measurement is 1 inch. Show that at a distance of 2 feet to the right of the origin, the height of the graph of f is 48ft but the height of the graph of g is about 265mi.
20) Compare the functions f(x)=x^10 and g(x)=e^x by graphing both f and g in several viewing rectangles. When does the graph of g finally surpass the graph of f?
