    Hi,

    I did composite functions in Y10 but haven't understood them since. I'm in Y11 and need to learn how to solve them for an upcoming exam.

    Thanks in advance

    check edit
    Let f(x)=x^2 and g(x)=2x+1

    Then fg(x)=f[g(x)]=f[2x+1]=(2x+1)^2

    Or gf(x)=g[f(x)]=g[x^2]=2x^2+1

    Composite functions: one function in another.
