Determine the coordinates of the vertex for each quadratic function and whether the parabola has a maximum or minimum. 4. y = x² +6x-2

minimum, coordinates of vertex: (-3,-11)

explanation:

x coordinates on vertex:

solving steps:

Find y-coordinate on vertex:

coordinates: (-3,-11) thus minimum

vertex = (-3, -11)

minimum

Step-by-step explanation:

The vertex of a parabola is its turning point (stationary point).

Therefore, the x-coordinate of the vertex can be determined by differentiating the function, setting it zero and solving for x:

Substitute found value for x into the original function to find the y-coordinate:

Therefore, the vertex is (-3, -11)

As the leading term of the quadratic function () is positive, the parabola will open upwards, so the vertex is its minimum point.

range is infinite on both x and y axis positive and negative

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
