Answer: C... {y|y ≥ -1}

Step-by-step explanation:

f(x) is a quadratic equation with the x-side squared and a is positive which means that the graph of the function is a parabola facing up. The range of f(x) is given by {y|y ≥ k}, where k is the y-coordinate of the vertex.

in vertex form (h, k) = (-1, -11)

This meaning the range ={y|y ≥ -11}
