    Composite Functions

    The graphs of the functions f and g are shown at the right. Use these graphs to determine the values of the following composite functions.

    f[g(2)]

    There are two graphs, one labelled f(x) one labelled g(x).

    Obviously, I can't post the graphs but I'd just like to know what I'm supposed to be doing. She didn't tell us.

    Look for the value at g(2)=5(example) then f(g(2))=f(5) since g(2)=5
