Answer:
159
Step-by-step explanation:
[tex](g\circ f)(2)[/tex] is just another way to express [tex]g(f(2))[/tex]
This means that you solve what [tex]f(2)[/tex] is first then input that answer into [tex]g[/tex].
[tex]f(2)= (2) + 8 = 10\\g(f(2)) = g(10) = 2(10)^2 - 3(10) -11 = 170 - 11 = 159\\[/tex]
Therefore [tex](g\circ f)(2)[/tex] is 159
