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.
Accepted Solution
A:
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).
