Question 64963
If this is what you meant:
Given {{{f(x)=(-x-4)/(-x)}}} and {{{g(x)=-4x^2-5x-1}}} find f(2) and g(-2)
{{{f(2)=(-(2)-4)/(-(2))}}}  Substitute 2 in for x in f(x) and simplify.
{{{f(2)=(-2-4)/(-2)}}}
{{{f(2)=(-6)/(-2)}}}
{{{highlight(f(2)=3)}}}
{{{g(-2)=-4(-2)^2-5(-2)-1}}}  Substitute -2 in for x in g(x) and simplify.
{{{g(-2)=-4(4)-5(-2)-1}}}
{{{g(-2)=-16+10-1}}}
{{{highlight(g(-2)=-7)}}}
Happy Calculating!!!
