    function graph

    I attached a graph from the problem. Sorry that the graph is so small

    Here's the question:
    The figure below shows the graph of y=g(x). If the function h is defined by h(x)=g(2x)+2, what is the value of h(1)?

    I dont get why the correct answer is 3, and please show steps. THank you thank you thank you in advance!!!

    h(1) = g\left( {2\left[ 1 \right]} \right) + 2 = 1 + 2 = 3

    You look at the graph! You tell us what g(2) equals.

    Oh haha thanks! It equals to one, because when you look at the graph, g(2) is 1.
