Find the vertex form.
y=(x+2)^2−11
plz mark me as brainliest :)
You need three non-collinear points to name a plane.
Non-collinear means "not on the same straight line". So these three points can't all lie on the same straight line. If three points do lie on the same straight line, then it is impossible to generate a single unique plane.
Answer:
D. No, because group A is already the control group.
