a) downward
b) x-intercepts: (-1, 0), (-3, 0)
y-intercept: (0, -3)
c) x = -2
d) Vertex: (-2, 1)
Explanation:
a) The parabola is facing down. Hence, it is downward
b) x-intercept: This is the value of x when y = 0
From the graph, at x = -1, y = 0
at x = -3, y = 0
x-intercepts: (-1, 0), (-3, 0)
y-intercept: This is the value of y when x = 0
It is also the point on the line crosses the y axis.
From the graph, the line crosses it at y = -3
y-intercpet: (0, -3)
c) Equation of axis of symmetry is the point the vertical line divides the parabola into mirror images.
From the graph, this is atr x = -2
Equation: x = -2
d) The vertex is the tip of the parabola
vertex: (h, k)
The tip is at x = -2, y = 1
Vertex: (-2, 1)
