Question 995047: Identify the vertex, axis of symmetry , y-intercept, x-intercepts, and opening of each parabola, then sketch the graph.
f(x) = (x+1)^2 - 9
Answer by josgarithmetic(39620)   (Show Source):
You can put this solution on YOUR website! The parabolic function is already in standard form, so all that information asked is easy to find. Intercepts on x you solve for f(x)=0. Vertex and symmetry axis, you just read from the function definition. Leading coefficient will be  , so parabola opens upward.
vertex (-1,-9)
axis of symmetry x=-1
roots -4 and +2
y-intercept evaluate f(0). y=-8 where x=0,.
You have enough information, or data, to make a sketch of the graph.
