y² = x
--> y = ±√x
Because there are *two* square roots for any positive number (positive and negative) this will not be a function.
A function is an equation that gives a unique answer. A relation does not. Example: y = 3x + 1 is a function. If I give you x, you can determine y. And that y is unique to that x. So if x = 1, you know y = 4. No other of x gives y = 4 as an answer. So y = 3x + 1 is a function. Example: y = 4x2. So if I give you x = 1, y = 4. But y = 4 if I also give you x = -1. So y = 4x2 is not a function, it is a relation.
A=r mod z R= a relation which is reflexive symmetric but not transitive
explain formula transformation
give an example of calculation of mathematics
Square numbers can't be prime. They have too many factors.

My teacher asked me to explain why I was late for class.Photosynthesis is difficult to explain.
You need to give an example of the rule and the function you want.
shiting it
No, because there is no such thing.
give me an example of a time when your had to explain some new procedures to your co-workers foe quality service delivery, how did you go about it ?
explain formula transformation
f(x) = 2x it is linear function
its a shape that cannot explain
Is it possible for a quadratic equation to have no real solution? please give an example and explain. Thank you
no... because no one can explaine the hess'slaw
