Vertex form

form looks like?
can we determine direction? if so, how?
can we find the y-intercept from this form? if so, how?
can we find coordinate point for the vertex? if so, how?
can we identify the axis of symmetry from this form? if so, how?
can we find the x-intercepts from this form? if so, how?
any other notes to add?
convert this equation into vertex form: y = x2 + 6x + 8
convert this equations into vertex form: f(x) = x2 + 4x - 16
