Answer:
• The vertex is (-3, -4).
,
• The y-intercept is (0,5).
,
• The x-intercepts are (-5,0) and (-1,0)
,
• The equation for the axis of symmetry is x=-3
Explanation:
Given the graph of the quadratic function below:
(a)Vertex
The vertex is the lowest/highest point on the parabola.
The vertex is (-3, -4).
(b)y-intercept
The line crosses the y-axis at y=5. At this point, the value of x is 0.
The y-intercept is (0,5).
(c)x-intercepts
The x-intercepts are the points where the line crosses the x-axis.
The x-intercepts are (-5,0) and (-1,0).
(d)The equation for the axis of symmetry
The equation for the axis of symmetry is the value of x at the vertex of the parabola.
Thus, the equation for the axis of symmetry is:
