Vertex (-10, 6)

#### Explanation:

x-coordinate of vertex:

(x + 10) = 0 --> x = -10

y-coordinate of vertex: y = 6

To find y-intercept, make x = 0 --> y = 300 + 6 = 306

To find x-intercept, make y = 0 and solve the quadratic equation:

parabola opens upward and is completely above the x-axis, regardless of the values of x.
