Best ResponseYou've already chosen the best response.1First find j(5). Remember that this is just "shorthand" that says "Plug x = 5 into the j equation". We get j(5) = 4*5 = 20. Now, we can find h[j(5)], which means "Plug x = j(5) into the h equation". Well, we know that j(5) is just 20. So we will plug in x = 20 into the h equation. This gives us: h[j(5)] = h[20] = 20  1 = 21. This is our final answer.
