Which statement is correct about the function y = x2 – 2x – 143?
a)in factored form, the function is y = (x – 13)(x + 11), so the zeros of the function are x = –13 and x = 11.
b)in factored form, the function is y = (x + 13)(x – 11), so the zeros of the function are x = –13 and x = 11.
c)in factored form, the function is y = (x – 13)(x + 11), so the zeros of the function are x = 13 and x = –11.
d)in factored form, the function is y = (x + 13)(x – 11), so the zeros of the function are x = 13 and x = –11.

C: f(x) = (x - 13)(x + 11)
Step-by-step explanation:
Please use " ^ " to indicate exponentiation: y = x^2 – 2x – 143.
x^2 – 2x – 143 factors into (x - 13)(x + 11). Note that -13x + 11x = -2x, which matches the middle term of the given function.
Thus, the zeros are {-11, 13}
Answer C is correct: f(x) = (x - 13)(x + 11).
