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).

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
