Describe the graph of a function with an axis of symmetry whose x-value is the opposite of the axis of symmetry of h(x). write the function in standard form to support you answer h(x)=-3x^2-12x+4
Is -b opposite of b?
yes?
i know the axis of symetry is -2
Then it's just like your question from last night, but switch the signs.
which sign?
so -3x^2+12x+4?
I think so, double check, what is the new functions axis of sym.?
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
which gives an axis of.... +2
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?
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.
