If 𝑓(𝑥) = 3𝑥 𝑎𝑛𝑑 𝑔(𝑥) = 5𝑥 − 1, 𝑡h𝑒𝑛 𝑓𝑖𝑛𝑑 𝑓(𝑔(3))𝑎𝑛𝑑 𝑔(𝑓(4)).

Answer 1

Hello, thank you for taking the time to post your question!

f(g(3)) = f(5(3) – 1) = f(14) = 3(14) = 42

g(f(4)) = g(12) = 5(12) – 1 = 59

I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)
