Question

The equation for the axis of symmetry for the graph of a quadratic function is x = –2. Which of the following could not be the equation of the function?

Answer 1

vertex form
y=a(x-h)^2+k
vertex is (h,k)
axis of symmetry is s the x value of h
y=a(x-(-2))^2+k
y=a(x+2)^2+k

anything that has
y=a(x+2)^2+k
