    Assuming you mean for x=3

    f (3) = 2 (3) ^2-3 (3) + 4

    f (3) = 2 (9) - 9+4

    f (3) = 18-5

    f (3) = 13

    it is 13

    To evaluate the function for x = 3a, substitute the 3a to the all the x's of the function. Such that,

    f (3a) = 2 (3a) ² - 3 (3a) + 4

    Simplifying to obtain the final answer,

    f (3a) = 18a² - 9a + 4
