Well gosh, I feel stupid. It's been 3 months since I last did quadradic functions, oh how i hate quadradic function. well anyways to get to the point, i seem to have forgotten how to do this simple math and was wondering if someone could help me with this question: "Find a, b and c so that the graph of the quadratic function f(x) = ax2 + bx + c has a vertex at (-2,1) and passes through the point (0,-3)"
I need this answered ASAP, it's somewhat useless to me if someone helps solve and explain to me TOMORROW >_< so yeah please and thank you!
