so today i was taking my final for AP Calculus AB (im in ABBC so i do AB first semester and BC second, calc 1 and 2 respectively) and theres a question that goes like
if the second derivative of f(x) is shown on the graph to the right (horizontal line at y=1) which of the folowing graphs is a possiblity of f(x)?
easy question, i narrowed it down to a parabola and none of these are a possibility
being the math perfectionist i am i tested out the points on the parabola, with proper antiderivates done and stuff, so f(x)=.5(x^2) + C(sub 1)x + C (sub 2)
idk how to do subscript/superscript so i did the best i could with that
the graph of the parabola had the points (0,0) (2,2) and (3,6) and
c sub 2 is 0 cuz (0,0)
but C sub 1 is not equal at x=2 and at x=3
so i put none of the graphs were a possibility
so after the test im talking with my teacher and people, and she says it was the parabola
she wouldnt listen to me when i was telling her why it wasnt because "it was a previos AP exam question, the answer is A"
TL;DR
whoever makes these AP calculus exams needs to l2graph
|:<
oh, and i need to make an A in this calc class to be eligible for DL Calc (taking calc 3 in high school with GA tech )
and i have like a 87 or something in that class.
i need a 95+ on the test to make an A in the class
so yeah, **** you ap calc exam makers
