What is the value of f[g(5)] for the functions f(x) = 2x + 1 and g(x) = 2x - 5 ? Please I don't get it at all.

    so first solve function g(x) with x = 5 then whatever you get from that, substitute into f(x) and solve that

    g(5)=2(5)-5=10-5=5

    no 5 is g(5):) now f(g(5))=f(5)=2(5)+1=11 which is the answer
