Question

I don't understand how to do this at all. Please help.

Create a quadratic function, f(x), in vertex form. The a should be between 4 and -4, the h will be your birth month, and the k will be your birth day. Write your equation below.

Answer 2

ok... so vertex form of a parabola is

\[y = a(x - h)^2 + k\]

which has the vertex at (h, k) a is a constant

so h = 7 and k = 15


just substitute them

then pick a value for a

I'd pick a = 0, so y = 15 is the equation....

but you might like something else of a
