    what does this production function look like on a graph?

    f(x1, x2) = 12x1^(1/2) + 4x2^(1/2)

    That would be a 3 dimensional graph. Do you have a graphing calculator?

    Not with me, what about if the last term, 4x2^(1/2) is left out of the equation, where output is y-axis and x1 is x-axis?

    Then it would look like the graph of squareroot of x with magnitude 12 times greater.



    That's what sqrt(x) looks like. I hope you know that part at least.

    without the last term the equation is:

    f(x1, x2) = 12x1^(1/2)

    in 3 dimensions that is z = 12x^(1/2)

    which is just like y = 12x^(1/2) just graph it along the Z and X axis

    Z|

    |___________ y axis

    / x axis

    Man your good. I didnt remember this one.

    The last time I remember graphing anything in 3D was prolly freshman year.

    on that graph x1 is the horizontal axis that goes up and to the right, and x2 is the horizontal axis that goes up and to the left. Z is vertical.

    I forgot to label them.

    do you mean df/dx1? There is no y in your problem.

    df/dx1 = 12*(1/2)*x1^(-1/2)
