Question 149988
1. for f(x)=3^xn __ at x=0, f(x)=1 __ as x gets more negative, f(x) approaches zero (negative x-axis is horizontal asymptote)
__ no asymptote for positive x


for g(x)=log52x __ as x approaches zero, g(x) approaches -∞ (negative y-axis is vertical asymptote)
__ logarithms are not defined for negative arguments (negative numbers don't have logs)
__ no asymptote for positive x


2.  there are 45 (180/4) 4 min periods in 3 hr __ the cells are doubling every 4 min
