**Define a binary relation P from R to R as follows: for all real numbers x and y, (๐ฅ, ๐ฆ) โ ๐ โ ๐ฅ = ๐ฆ^2 . Is P a function? Explain.**

The **Answer to the Question**

is below this banner.

**Here's the Solution to this Question**

Function is a some rule according to which for every value from domain exists exactly one value from the range that matches to it in terms of the rule

In the given case x is a domain, y is a range,ย $x=y^{2}$ย is a rule. We can tell that if x = 4, than y can be 2 or (-2). So, the condition of the function isn't met.

P is not a function
