write the equation of a parabola with the shape as f(x)= -2xsquared but with vertex (-3,2)

Question

anonymous · Answer

put y instead of f(x), the equation is
$$y=-2x^2$$
with vertex (-3,2) and the same shape, (just change the vertex from (0,0) to (-3,2) ):
$$y-2=-2(x-(-3))^2 \implies y-2=-2(x+3)^2$$
