Hi, there is a question.
00:01
The formula for the graph of marginal cost is being given and which is in the shape of parabola like this.
00:12
I will be first finding out the equation for c prime q which is our let us say y equal to c prime q like this.
00:24
Now the vertex seems to be equal to 25, 10 and the parabola this is 0, 40 and one more thing one more point could be 40, 20.
00:50
Okay, 40, 20 and it is upward opening parabola.
00:55
I will be using y and x and then i will be just plugging in.
01:02
This is h and k.
01:05
So since it is upward opening parabola, x minus h whole square equal to 4p y minus k.
01:13
H, k are 25 and 10.
01:16
X minus 25 whole square 4p y minus 10.
01:22
It is passing through 0, 40.
01:25
This equation number one, let us plug in x equal to 0 and y equal to 40.
01:31
0 minus 25 whole square equal to 4p.
01:36
40 minus 10.
01:39
This is 625 equal to 4p into 30.
01:47
4p equal to 625 by 30.
01:53
125, 6.
01:57
Now let us plug in equation number one.
02:01
25 whole square equal to 125 by 6 y minus 10...
