Answer:
120
Step-by-step explanation:
The discriminant can be written as an expression: b² - 4ac.
We know that a = -7, b = 8, c = 2, since the function f(x) = -7x² + 8x + 2 is in standard form: ax² + bx + 2.
Now let's evaluate the discriminant:
b² - 4ac
= 8² - 4(-7)(2) (Simplify)
= 64 - 4(-14)
= 64 + 56
= 120
