F(x)=x² + 6x-11
Write the equation in vertex form.

Step-by-step explanation:

we have

To convert to vertex form complete the square

Rewrite as perfect squares

----> equation in vertex form

The vertex is the point (-3,-20) (is a minimum)

The answer is $25,000.

Step-by-step explanation:

As given, the Payroll Department's budget is $100,000, and it issues 4,000 checks every other week. The lighting plant has 1,000 employees.
