Answer:
Option A.
Step-by-step explanation:
The excluded value of any function comes from the denominator.There can not be a 0 in denominator as this will make the function undefined.
To find the x value that will make the denominator 0 we put the denominator =0 and solve for x .
A)
Or (x+2)(x-2)=0
Solving for x :
x+2=0 x-2=0
x=-2. x=2.
In this function x=-2 will make the denominator 0 and hence will be the excluded value.
First things first when multiplying and dividing positive and negative numbers if the two signs are the same it's positive, and if both signs are different it's negative.
you simply just multiply and divide the same as you would normally you just have to pay attention now if the answer is positive or negative.
X^2 + 7x + 10
Find the factors of 10 that add up to 10.
1* 10, 2*5
The factors are 2*5
(x+2)(x+5)
