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.

Answer:

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).
