The value of the function f(g) after simplifying and putting 2 in place of <em>x</em> is -20 and the value of f(g(2)) is 418.
<h3>What is composite function?</h3>When a function is written inside the another function, then such function is called the composite function.
The first function given in the problem is,
The second function given,
To find out the value of g(2), put the 2 on place of variable x in the above equation as,
The composite function f(g(x)) can be given as,
Thus, the value of the function f(g) after simplifying and putting 2 in place of <em>x</em> is -20 and the value of f(g(2)) is 418.

Answer:
Coordinates of other end point L = ( -19, 13 )
Explanation:
The mid point of the coordinates (a,b) and (c,d) is given by
Here we have (a,b) = (1,-7) and = (-9,3) , we need to find (c,d).
So coordinates of other end point L = ( -19, 13 )
