Question 540936
<pre>
f(x) = |x-8| and g(x) = 4x+9 then g(f(2))=?

We find f(2) and then we substitute that for x in g(x) = 4x+9 

First find f(2), by substituting 2 for x in

f(x) = |x-8|

f(2) = |2-8|
f(2) = |-6|
f(2) = 6

Now substitute f(2) for x in the left side of g(x) = 4x+9 and 6 in the right
side of g(x) = 4x+9

   g(x) = 4x+9

g(f(2)) = 4(6)+9

g(f(2)) = 24 + 9

g(f(2)) = 33
