a Function f is defined as f(x)=3*2^x
a)is f increasing or decreasing?
b)write equation for the horizontal asymptote
c)describe the end behavior of

a)f'(x)=3*ln(2)*2^x>0
b)y=0 (limf(x)=0 if x> inf)
c)? 
please explain your b and a.

a)If f'(x)>0 then f(x) is increasing
b)x  f(x)
0  3
1  3/2
2  3/4
3  3/8
10  3/1,024
20  3/1,048,576
30  3/1,073,741,824
33  3/8,589,934,592
