Answer 1

Answer:

To find the set builder form for the given expression

From the given expression it is clear that the denominator is equal to sum of 1 and square of numerator

Denominator = (Numerator)² + 1

If we consider numerator as 'n' then the denominator is n²+1

Given the set in roaster for i.e

we have to describe the above set in set-builder form

Let the set be X

plz mark as the brainliest answer or follow me plz plz.

Answer 2

Answer:

To find the set builder form for the given expression

From the given expression it is clear that the denominator is equal to sum of 1 and square of numerator

Denominator = (Numerator)² + 1

If we consider numerator as 'n' then the denominator is n²+1

Then the given condition {1/2,2/5,3/10,4/17,5/26,6/37,7/50} is the from of [\frac{n}{n^2 + 1} and then put the value of 'n' varies from 1 to 10.
