Answer is correct. A. But the reasoning is wrong. It could pass (0, 4) even with x-intercep(s). You have to check with discriminant b^2-4ac

You can elimimate C and D through common sense. Check the discriminant (b^2-4ac) of A and B and the one that is negative (A) is the answer

You could also use the discriminant in the quadratic formula to see that A doesn’t have any real solutions when y = 0

How do u know that the vertex is above the x axis? The c term in standard form doesn’t tell you anything about the location of the vertex
