I would really like to thank you for your videos. Your teaching style is absolutely great, you talk with a steady pace which allows us to have a second to process what you're saying. I am glad to be subscribed to you, i am truly grateful, thank you! :)

Thanks for your comment. It is always a struggle to judge the right pace for the videos. In a classroom it is easier because students can ask questions and even ask me to slow down. I am adding more tutorials all the time and going from introductory all the way through the Calculus proof. So more to come.... I also have channels on Statistics, Algebra and Calculus. You can see links to all those on our Facebook Fan Page (see link in video description). Thanks again!

For anyone who wants to know because I did, the reason you multiply by .5 is because you need to use the number that makes it equal 1. 0.5 x 2 = 1 .. I at first thought you always use 0.5.

So confused at 2:56, if you want the 2 from the 2Qd to go to the other side, don’t you divide that, instead of multiplying with 1/2???
@economicsfun11 жыл бұрын
That is a good question. The short answer is no the demand curve is the derivative of the utility function. The demand function is derived from indifference curves and budget lines (something that is taught during consumer theory).

The purpose is just mathematical. Sometimes the equations are easier to work with when they of the form Qd = 10-1/2P it is easier to get the quantity if you have the price. The opposite is true if you are trying to find price and know quantity. It would be easier to work with P= -2Qd+ 20. This form is easier to find the slope because it is in the y = mx+b format.

Thank you for the great video! I will definitely check out your other pnes as I am an econ major dying in college. My question is does the inverse demand curve look exactly like the regular demand curve? Since it's just a change in perspective.

Good video, one thing I don't really understand... Why do we call them an inverse when they're simply the same equation but just re-arranged differently? Surely an inverse would imply that the actual demand and supply graphs would change.
@economicsfun10 жыл бұрын
You would solve for P. Subtract 200 from both sides of the equation and then divide by - 8. Make sense?
@gloriasheen63366 жыл бұрын
how do you know WHEN to use the inverse function and when not to? arent they the same? my question is asking for the c in Q=c+dP (The general equation of the supply curve) and they somehow rearrange the function in terms of P, but why Can't I find c with the function in terms of Q? (P and Q are given)

I was simply told...you find the inverse of the generally given supply and demand function to simply denote the price and quantity values 😗... simple

@AllAroundKnowledge7 жыл бұрын
So, when you are given, for example, a demand function (where the slope is always negative), the demand function tells us for some price level, we are looking to find how much the demand is. However, when we find the inverse of a demand function, this is telling us, to get a certain level of demand, we need to be at whatever price point. Is this accurate? If so, then does the same logic apply to the supply function and the supply inverse function?

Really great video, good pacing. can i just ask what the purpose of switching between the equation of the demand curve and the inverse demand curve is? Is there some other purpose to use one over the other rather than for graphing purposes (like you said, putting the equation in the y = mx + b form, making it easier to understand)?
@omarslive42754 жыл бұрын
We know that the slope of a downward curve is negative and we also know that quantity, Q=a+bp. In this function why does the slope b have a positive sign?

How would you graph this if you don't know the price? For example, I have a demand function: P=7-2Q and a supply function: P=4+Q?

+Olushola Bunmi Abayomi Qd-.25p=50,-.25p=50-Q;::::::Divide both side by -.25 then you get 50/.25=200 and p stand for 1, so 1/.25=4 thats how you get the inverse of P=200-4Q
