Question 45590
{{{g(x) = (1 - x)/(x + 1)}}}
g(2)
{{{g(2) = (1 - 2)/(2 + 1) = -1/3}}}
g(-2)
{{{g(-2) = (1 + 2)/(-2 + 1) = -3}}}
g(1/2)
{{{g(1/2) = (1 - 1/2)/(1/2 + 1) = (1/2)/(3/2) = 1/3}}}
g(a)
{{{g(a) = (1 - a)/(a + 1)}}}
g(a-1)
{{{g(a-1) = (1 - (a-1))/(a-1 + 1) = (1 - a + 1)/(a) = (2 - a)/a}}}
g(-1)
{{{g(-1) = (1 + 1)/(-1 + 1) = 2/0}}} Undefined
