Sanjay begins to correctly graph the function f(x) = (x + 1)2 – 3. based on the axis of symmetry and the vertex, which graph could be sanjay’s?

Please use " ^ " to denote exponentiation:    f(x) = (x + 1)^2 – 3

You can read off the coordinates of the vertex immediately:  (-1, -3).  Thus, the axis of symm. is the vertical line x = -1.  Plot (-1, -3) and draw a vertical line thru this point.  The graph will open UP and will be symm. about the line x = -1.

Your question asks, "which graph?"   but you haven't shared the possible answer choices.  If at all possible, learn how to upload images to to illustrate your questions.
