thegameishere Group Title

Let h(x)=f(x)⋅g(x), and k(x)=f(x)/g(x). Use the figures below to find the values of the indicated derivatives. http://www.flickr.com/photos/57417292@N03/6212910338/in/photostream http://www.flickr.com/photos/57417292@N03/6212910354/in/photostream These two are the graphs

    Remember that the derivative is the slope of a line.

    yes I've tried that too and I believe the slope of the line is equal to the slope of the tangent line too

    and the slope of the tangent line equals the derivative

    Do they want you to get the derivative at certain points or what?

    I got 2/3 for prime but whats the te value of g(1)

    They want g(1) and k(1)? They don't want the derivative?

    they want k(1) and k is equal to f(x)/g(x) I got slope 2/3 for f(x)

    and F'(1) is zero because thats where u have an x intercept

    and the equation simplifies to f(x)g(x)

    Okay, so what are the graphs you posted?

    those are the functions of f(x) and g(x) they are the functions

    So since f(1) = 1 and g(1) = 1.25, k(1) = 1 / 1.25

    f'(1) = 2/3 since it rises 2 and runs 3 when x is 1

    How is g(1) = 1.25 when its not given

    Well, from the left side you can see the slope is -2, so it has to hit at the half way point

    Then it goes through the origin

    So it is rising 2/1.5
