Question 626914
Describe the following characteristics of the logarithmic function y = logax. 
1) Domain: (0,∞) 
2) Range: (-∞,∞)
3) x-intercept: 1 
4) Horizontal asymptote: none
5) Vertical asymptote: y-axis or x=0
6) General shape: starting from (0,-∞) curve becomes less negative until it crosses the x=axis at (1,0), at which point the curve becomes increasingly positive to ∞.
