Question

What are the zeros of f(x)=x²-x-127

OA. x=-4 and x = 3
OB. x=-3 and x=4
OC. x=-2 and x = 6
OD. x=-6 and x = 2

Answer 1

The zeros of the function f(x) = x² - x - 127 are x = -4 and x = 3.

Step-by-step explanation:

The zeros of a function are the values of x that make the function equal to zero. To find the zeros of the function f(x) = x² - x - 127, we set the function equal to zero and solve for x.

x² - x - 127 = 0

We can solve this quadratic equation by factoring or by using the quadratic formula. Factoring the equation gives us (x - 3)(x + 4) = 0, which means the zeros of the function are x = 3 and x = -4. Therefore, the correct answer is OA. x = -4 and x = 3.
