Question 153088
Find the equations of the asymptotes of:
a) {{{g(x) = log(x-3)}}} For what value of x is the function undefined?
{{{g(3) = log(3-3)}}}={{{log(0)}}} The {{{log(0)}}} is undefined, so at x = 3 there is a vertical asymptote at {{{highlight(x = 3)}}} and this is the equation of the asymptote.
b) {{{g(x) = -log(x)}}} For what value of x is the function undefined?
{{{g(0) = -log(0)}}} The function is undefined at x = 0 so there is a vertical asymptote at {{{highlight(x = 0)}}} and this is the equation of the asymptote.
