Is -b opposite of b?
OpenStudy (anonymous):
yes?
OpenStudy (anonymous):
i know the axis of symetry is -2
OpenStudy (anonymous):
Then it's just like your question from last night, but switch the signs.
OpenStudy (anonymous):
which sign?

so -3x^2+12x+4?
OpenStudy (anonymous):
I think so, double check, what is the new functions axis of sym.?
OpenStudy (anonymous):
thats the thing i dont understand i have the symetry which is -2 and the equation above in standard form is y=-3(x+2)^2+16
OpenStudy (anonymous):
which gives an axis of.... +2
OpenStudy (anonymous):
Also, the answer is not unique, pick any parabola with axis (i.e. max or min) at 2. ex
\[(x-2)^2\]

so plug the -2 in x?
OpenStudy (anonymous):
um. we want +2. and it's not necessarily a root, just the max/min. So you want 2 to be the vertex, OR a root of the derivative = 0 if you know/like calculus.
