(f) Set the value of a to $-2, b$ to 2 , and $c$ to -1 . Determine the value of the discriminant. The value of discriminant is (Type an integer or a decimal.)

Step 1 ：Given that a = -2, b = 2, and c = -1.

Step 2 ：The discriminant of a quadratic equation is given by the formula \(D = b^2 - 4ac\).

Step 3 ：Substitute these values into the formula to find the value of the discriminant.

Step 4 ：So, \(D = (2)^2 - 4*(-2)*(-1)\).

Step 5 ：Therefore, the value of the discriminant is \(\boxed{-4}\).
