Question

is p={x:x²-2x, x belongs to r} is not an empty set give the reasons​

Answer 1

Heya mate ..

Here is your answer ...

$x { }^{2} - 2x$

doesn't belong to empty set ..

For example , let's take x as 2

then

$x ^{2} - 2x$

$2 ^{2} - 2(2) = 0$

so there an element exists ...

So , the given set is not an empty set.

Hope it helps you ...
