This shows the bacterial count is increasing with time, and the rate of bacteria growth is also an increasing function. . l r 1 [12] [lm w :0 xyD :- 1 [13] The line 1:21 is a vertical asymptote of f(x) = 1 . x _ 1 [14] The line y=D is a horizontal asymptote of [(15) = ] . x _ [15] There are only two types of asymptotes: horizontal and vertical asymptotes
