Answer:
x= -2 & x = 6
Step-by-step explanation:
To find undefined points, you need to know when the bottom of the fraction is equal to 0, because you can't divide by 0! (The numerator is irrelevant.) In order to do this, you can factor the denominator of x^2 - 4x - 12. What factors of -12 add up to -4? That would be -6 and 2, so you can factor it out to (x-6)(x+2). Because the coefficient of x in both of these cases is 1, you can take the shortcut of just taking the opposite sign of the two numbers being added to x in these factors, giving you 6 and -2 for your undefined values.
Let me know if you need a more thorough explanation, as I sort of skipped through some wordy things there to give a more concise answer.
To solve this problem follow the steps below.
Step 1:List out all of the factors for -36
-36: 1,2,3,4,6,9,12,18,36
-1,-2,-3,-4,-6,-9,-12,-18,-36
Step 2: Start going through a process of guessing and checking (basically take any two factors and add them together to see if they equal 13)
1 plus 12=13
9 plus 4=13
Step 3:Check your calculations and make sure you didn't make any errors
13-12=1 and 13-1=12
13-9=4 and 13-4=9
Answer: 1 and 12
4 and 9

Answer:
Step-by-step explanation:
As written, they all are linear functions.
If we assume that x3 is supposed to be interpreted as x³ = x^3, and that x2 is supposed to be x² = x^2, then the equations containing those terms are not linear equations.
The equation y = 1/5x is usually interpreted to mean y = (1/5)x. If it is intended to be y = 1/(5x), then it is not a linear function either.
___
A linear function is a sum of terms that are either constant or containing a single variable to the first power.
