Need badly 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.

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

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).

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
