Find the x-intercepts (if any) for the graph of the quadratic function.
1.f(x) = (x + 2)2 - 4
I got (0,0) and (-4,0)
Find the y-intercept for the graph of the quadratic function.
5.y + 9 = (x + 3)2
I got (0,0)
Find the domain and range of the quadratic function whose graph is described.
7.The vertex is (1, -15) and the graph opens up.
I got domain: (-infinity, pos.infinity)
range: [-15, pos. infinity)
