Algebra check Damon
No it is not It sure looks obvious to me that was what Damon told you. To have a one-to-one, both the relation and its inverse must be functions. Yours is not

Reiny or Damon or Bobpursley
Express the series 11 + 18 + 27 +...+ 171 using sigma notation. Usually you would take 27-18 and thats the step between numbers, right? (I think its the k-value?) But 27-18=9 and 18-11=7. Are we stepping by k+2 here? Like k, k+2 k+4, k+6...? Please help me. I'm not confident ...

Damon, when I opened the page and started to answer this question, I left it alone to watch the end of the WorldCup football game, and when I resumed I did not refresh the page, thus did not see your answer was already posted.

Calculus
Damon I respectfully disagree Your parabola opens sideways I think you meant to say: y-1 = a(x-6)^2 then at (0,-35) -36 = a(36) a = -1 so y-1 = -(x-6)^2 y = -(x-6)^2 + 1

Did you mean 2(x^2)y 12 + 12xy + 18y ? If so, then = 2y(x^2 + 6x + 9) = 2y(x+3)^2 If you meant it the way you typed it, then use Damon's solution.

Math
If the question is g(x) = 1/(x-3) + 1 then the vertical asymptote is x = 3 and the horizontal is y = 1 (I believe Damon asked you yesterday for a clarification about the confusing denominator, but today you typed it exactly the same way.)

lou, your answer of -(x-5)(x+5) is the same as the answer of (5-x)(5+x) that Damon and anonymous gave you if you want to factor out the -1 at the start, you can do that 25 - x^2 = -(x^2 - 25) = -(x+5)(x-5) really makes no difference
