Choose The Inverse Of Y X2 10x

y = x2 - "10x. ??????????

I do not understand this. Can anyone tell me how to find the opponent?

It's not easy. First, there are multiples of x-values for the same y-value, so there is no exact inverse function in the common domain. Here's how:

y = x 2 10x + 25 25

y = (x5) 2 25

y + 25 = (x5) 2

x5 = + / square (y + 25)

And you have two reversals:

For x = 5 + square (y + 25), x> = 5

I'm not an expert, but I'm sure it's a little over 1.

Then

y = x2 10x

y [ultimate] = (1) / (x2 10x)
