Question 4942
{{{f(x) = -5x - 3 }}} and {{{g(x) = x^2 + 10x}}}


(f o g)(x) means f[ g(x)] which means to take the g(x) formula and substitute it in the f(x) formula in place of the x.


{{{f(x) = -5x -3 }}}
{{{f( g(x)) = -5(x^2 + 10x) - 3}}}


Multiplying it out you get:
{{{f( g(x)) = -5x^2 - 50x - 3}}}
