The surface area is 1203cm good luck on your homeworek
I have included a graph to help you see what the domain and range would be
There are no minus y values.
0<y< infinity y is included in the reals.
The domain is
- infinity < x < infinity.
I don't want to say that either x or y can equal - or + infinity. Some teachers allow it. You have to ask your instructor what they will accept.
The blue line is y = 4^x
The red line is y = 2^x
The answer is the first and the third figure,attached

83.971
+ 10.900 (make believe there are two zeros)
