show me step by step how to find the domain of this function then graph it
g(x)=2x-4

  • math -

    The domain of a function is the set of all possible input values which allows the function formula to work.

    In this case your function are straight line.

    Domain of straight line : (-infinity,infinity)

    OR

    all values of x


    For graph find any two points eg.

    x = 0

    g ( x ) = 2 * 0 - 4 = 0 - 4 = - 4


    x = 1

    g ( x ) = 2 * 1 - 4 = 2 - 4 = - 2


    OR

    In google type:

    function graphs online

    When you see list of results click on:

    rechneronline.de/function-graphs

    When page be open in blue rectacangle type:

    2 x - 4

    Then click option : Draw

    You will see graph of your function
