Answer:

f(x) = \frac{x^{2} -5x-6}{x^{2} -4}

Step-by-step explanation:

Let's factorize the 1st option :

⇒ f(x) = \frac{x^{2} -5x-6}{x^{2} -4}

⇒ f(x) = \frac{x^{2}+x-6x-6 }{(x+2)(x-2)}

⇒ f(x) = \frac{(x+1)(x-6)}{(x+2)(x-2)}

===============================================================

Finding the zeros :

⇒ Factors of numerator should be equated to 0

  1. x + 1 = 0 ⇒ x = -1
  2. x - 6 = 0 ⇒ x = 6

=============================================================

Solution :

f(x) = \frac{x^{2} -5x-6}{x^{2} -4}

Answer:

first option

Step-by-step explanation:

the zeros are determined by the numerator of the rational function.

given that the zeros are x = - 1 and x = 6 , then the corresponding factors are

(x + 1) and (x - 6) , that is

(x + 1)(x - 6) ← expand using FOIL

= x² - 5x - 6

the rational function is then

f(x) = \frac{x^2-5x-6}{x^2-4}

Y= -3x + 4

The slope of the line is -3x which means that for every 1 x there are -3 y
The y intercept is 4 because the line intercepts the y axis at 0,4.
