Question

NEED HELP BADLY PLEASE ANSWER ITS ONLY ONE QUESTION

The vertex of a quadratic function is (-3,5). This means that:

The x-intercept is -3 and the minimum or maximum y value is 5.

The minimum or maximum value of the function is -3 and the axis of symmetry is y=5.

The minimum or maximum value of the function is -3 and the y-intercept is 5.

The axis of symmetry is x=-3 and the minimum or maximum y value is 5.

The x-intercept is -3 and the y-intercept is 5.

Answer 1

The axis of symmetry is x=-3 and the minimum or maximum y value is 5.

Explanation:

The vertex is the extreme point of the quadratic function. The graph is left/right symmetrical about the vertex, so the x-value defines the axis of symmetry. The y-value is the extreme, the maximum or minimum.

The graph shows two quadratic functions (red, blue), each with its vertex at (-3, 5). You can see that the line x=-3 is the axis of symmetry of each of them. You can also see that y=5 is the extreme value of the function (maximum or minimum).
