value. find that value and explain how you know.

The function has a maximum

The maximum value of the function is

Step-by-step explanation:

For a quadratic function of the form:

where a, b and c are the coefficients of the function, then:

If the function has a maximum

If the function has a minimum value

The minimum or maximum value will always be at the point:

In this case the function is:

Note that

The function has a maximum

The maximum is at the point:

The maximum value of the function is
