Answer:
Step-by-step explanation:
7. Where the graph is increasing: start from the center of the parabola which is the minimum, it starts at -4 which is the y-axis and it rises or increases to ∞. Therefore, it is (-4, ∞).
8. The axis of symmetry is in the middle of the parabola and it is a minimum. It is an x-coordinate of the vertex. Therefore, it is x = 5.
