The extreme value of the graph is at (8,-4). U The graph of the equation has a maximum. Submit​

The graph of the equation has a minimum.

When y = 0, the solutions are

The extreme value of the graph is (4,-12).

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

.

This polynomial has roots such that , given by the following formulas:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

It's vertex is the point

In which

Where

If a<0, the vertex is a maximum point, that is, the maximum value happens at , and it's value is .

y = x2 – 8x + 4

Quadratic equation with

a is positive, so it's graph has a minimum.

Solutions when y = 0

When y = 0, the solutions are

Extreme value:

The vertex. So

The extreme value of the graph is (4,-12).
