State the value of the discriminant of:
-2x² + x -4 = 0
-31
-24
66
76

-31

Step-by-step explanation:

Formula for finding the discriminant:

b² - 4ac

Let's identify our values.

a = -2

b = 1

c = -4

Time to plug in our values.

1² - 4(-2)(-4)

1 - 32

-31

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
