By adding(3) to both sides and subtracting(2xy)from both sides: x+3=5y-2xy x+3=y(5-2x) y=(x+3)/(5-2x) f^-1 (x)=(x+3)/(5-2x) Is my final answer right as it is multiplied by (-1)?

yes it is correct. if you ever want to check, just put a value for x and evaluate both versions to see if the answers match.

FYI: The inverse of a function of the form y = (Ax+B) / (Cx+D) is y = (-Dx+B) / (Cx-A). In your video, you have: y = (5x-3) / (2x+1) with A=5, B=-3, C=2, D=1 The inverse is: y = (-x-3) / (2x-5) Please watch my video entitled: "Inverse linear Ratios/Fractions theorem" for more details.

x^2 + 6x + 1. It seems that this function does not have an inverse or I can't do algebra

+[HQ]Life Dude use perfect square to break the eq down you will get y= (x+8)^1/2 -3 but its square root so it will Fail the horizontal line test so in conclusion that function doesnt have an inverse u can also try to see it graphically. Hope this helps

can someone explain to me why you can change xy-y =2 to y(x-1) =2? I don't get it...

She factored out a y. Think of it as this x3-3= 2 => factor what you see in common (3) => 3 (x-1)= 2 which means 3 times x (3x), 3 times -1 (-3), all equals 3x-3= 2

How did you get x-1 when you factored out the y ?

yx-y factor the common term. since y is common between both you end up with y(x-1) becuZ y * 1 is just y.

Dude, these ARE great!!! My Algebra students watch vids at home before we begin to explore each new concept and it's related standards (Flipped Model), as well as review later. Yaymath seems to be their FAVORITE. U and I think a lot alike. I don't put on such a great demo every day, but I DO try. :) Thanks for helping them learn and for helping me teach!!! I'd LOVE to hear from you to get more info, etc about your future plans for spreading this innovative "Anxiety Out" idea.
