Thank you for the opportunity to help you with your question!

Here are the answers of your questions:

1.) Does the function have a minimum or maximum value?

Yes the function has a maximum value.

2.) Where does the minimum or maximum value occur?

The maximum or minimum of a quadratic function occurs at x=−b/2a. If a is negative, the maximum value of the function is f(−b/2a). If a is positive, the minimum value of the function is f(−b/2a)

3.) What is the functions minimum or maximum value?

x = -(-4) / 2 (-2)

x = -1

f(max) = ax^2 + bx + c

f(max) = -2 (-1)^2 - 4(-1) -1

f(max) = -2 +4 -1

f(max) = 1 answer
