  1. 5. Which if the following is a true statement about the function y = 1/x?

    a. The domain is all real numbers.
    b. The range is all real numbers.
    c. The domain is all real numbers except 0.
    d. The range is all real numbers except 1.

    A: a?
    =============================
    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".
    I had no argument with the rest of your answers.

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

    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
