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:

In factor [tex]y=(x-13)(x+11)[/tex] and The zeros are x=13 and x=-11

C is correct.

Step-by-step explanation:

Given: [tex]y=x^2-2x-143[/tex]

Factor the function,

[tex]y=x^2-2x-143[/tex]

[tex]y=(x^2-13x)+(11x-143)[/tex]

[tex]y=x(x-13)+11(x-13)[/tex]

[tex]y=(x-13)(x+11)[/tex]

Factor of the given function is (x-13)(x+11)

If we find the zeros of the function, we will set each factor to zero.

x-13 = 0     and     x+11=0

x=13,-11

The zeros of the function are 13 and -11

Hence, In factor [tex]y=(x-13)(x+11)[/tex] and The zeros are x=13 and x=-11
