Can someone please help I really don’t understand this please explain it.

C)  29

Step-by-step explanation:

Given f(x) = 2x + 5 and g(x) = x² + x , find ( f o g)(-4)

( f o g)(-4) = f (g(-4))      f compose g

= f(x² + x)                      function g

= f(-4² + (-4))                 plug -4 into function g and simplify

= f(16 - 4)

= f(12)                            result of function g

= 2x + 5                        function f

= 2(12) + 5                     plug result of function g into function f and simplify

= 24 + 5

= 29
