2 1 point

Which of the following statements are true about the following graph?
2
-2
O
2+
-4
The graph has a maximum.
The graph has a minimum.
The graph has zeros at 1 and - 3.
The vertex is located at (-4,1)
The graph has a y-intercept at (0, -3).
The solutions of the quadratic function represented by the graph are -1 and 3.
The vertex is located at (1,-4)
• In the equation, "a" would be positive.
In the equation, "a" would be negative.

Answer 1

• The graph has a minimum.
• The graph has a y-intercept at (0, -3).
• The solutions ... are -1 and 3.
• The vertex is located at (1, -4).
• In the equation, 'a' would be positive.

Explanation:

When the graph has a low point, it has a minimum. 'a' is positive in that case. The coordinates of that low point are (1, -4). That point is the vertex.

The graph crosses the y-axis at y = -3, so the y-intercept is (0, -3).

The graph crosses the x-axis at (-1, 0) and (3, 0). These points represent the solution to the equation y = 0.

• The graph has a minimum.
• The graph has a y-intercept at (0, -3).
• The solutions ... are -1 and 3.
• The vertex is located at (1, -4).
• In the equation, 'a' would be positive.
