Answer:

-2

Step-by-step explanation:

Value of the function at x = 4 is 12

Value of the function at x = 8 is 4

change in y is  4 - 12 = -8

change in x is 8 - 4 = 4

x = 4 to x = 8 is -8/4 = -2

Which of the following is the reciprocal of x2 – 2x – 8?
Ann [662]
Hi again

x² - 2x - 8
Factor
= (x + 2)(x -4)
Answer : A is the correct option.


If you wanna check if A is the right answer, I will solve it for you and it will you give you the exact answer which will be x² - 2x - 8
(x+2)(x-4)
Distribute
(x)(x) + (x)(-4)+(2)(x)+(2)(-4)
= x² - 4x + 2x - 8
= x² - 2x - 8
Here it is, we find the exam answer.

Thus, (x+2)(x-4) is the reciprocal of x² -2x - 8


I hope that's help !
