Given $f\left(x\right) = x^{2} + x$ and $g\left(x\right) = x + 1$, find:

1. $g\left(f\left(x\right)\right)$

   Hint (a):

   Substitute $\left(x^{2} + x\right)$ for every x in the g function.

2. $f\left(g\left(x\right)\right)$

   Hint (b):

   Substitute $\left(x + 1\right)$ for every $x$ in the $f$function.

3. For what value(s) of $x$ will $f\left(g\left(x\right)\right) = 2$?

   Step (c):

   $x^{2} + 3x +2 = 2$

   Now set the equation equal to 0 and solve.
