=============================
No, undefined when x = 0, denominator is zero, exclude from domain, c

2. I'm sorry but I don't quite understand what you mean. Is the answer c?

Also, what about the other questions? Will you evaluate the answers of those as well?

3. Now wait a minute. Somewhere in your text book it says that if the denominator of a fraction is zero, that spot must be excluded from the domain of the function since the answer is undefined. Try dividing some number by zero on your calculator. Answer is "c".

4. So they are correct?

5. As far as I know, yes

6. Victoria ... What do you think these words of Damon's mean? "I had no argument with the rest of your answers."

7. I know what they mean. I just wanted to make sure that I didn't misunderstand him.

1/3 - 5/6 = 1/X SOLVE 1/3 - 5/6 = 1/X Let's remove the denominators by multiplying by 12X 12X*(1/3) - 12X*(5/6) = 12X*(1/X) Clear the fractions. 4X - 10X = 12 -6X=12 multipy by -1 6X=-12 Divide both sides by 6 6X/6 = -12/6 X = -2
