    Functions 1 and 2 are shown below: Function 1: f(x) = −3x^2 + 2 Which function has a larger maximum? Type your answer as 1 or 2.

    well, the graph shows you the maximum value of function 2, which is a little bit above 4, agreed?

    so to find the maximum value of function 1, we let x = 0 and calculate function 1

    The maximum for function 1 would be 0, right?

    function 1 is −3x^2 + 2 when x = 0, what is function 1? (it's not 0)

    -3(x^2) + 2 = -3(0^2) + 2 = ?

    let's break it into two parts, ok? first part: -3(0^2) = ?

    Please tell me its 0... 0 raised to the 2nd power is 0... 0 times -3 is 0... what am i doing wrong???

    when x=1 then it will be funtion 1 f(1)=-3(1)+2=-1

    now funtion 2 x=2 f(2)=-3(2)^2+2=-4

    so function 2 has maximum value

    So the answer is 4? @Vocaloid @sohailiftikhar

    nope, not quite... we're looking at function 1

    your question is which function has a maximum value to answer is function 2

    function 1 = -3(0^2) + 2 the first part is -3(0^2) = 0 the second part is + 2 so add them together to get

    the question is asking to find the maximum values of function 1 and 2, then to see which maximum is higher...

    Yes max for function 1 is -1 and max for function 2 is 4... So function 2 maximum is higher

    well, yeah, function 2 has the higher maximum

    yes

    function 1 has the maximum value of 2 because 3(0^2) + 2 = 2

    Oh!!!!!!!!! So for my answer I type 2...cuz function 2 is 4?
