Question 1207231
<pre>


f(x) = x + 1 and g(x) = x<sup>2</sup> + 6x, find g(f(x))
g(f(x)) means to substitute the right side of f(x) for x in the right side of g(x).

Take the right side of f(x), which is x+1, put parentheses around it, (x+1),
and in place of every x in the right side of g(x), put (x+1), so you have

x<sup>2</sup>+6x put (x+1). 

So

g(f(x)) = (x+1)<sup>2</sup>+6(x+1)

You simplify that right side, or wait, and somebody will simplify it for you
and you won't have to do anything but copy it and turn it in.
