Question

Is f(x)=√x2+1 a polynomial?

Answer 1

Answer:

Step-by-step explanation:

sqrt(x^2 + 1) is not a polynomial while

sqrt(x^2) + 1 = |x| + 1 is a polynomial.

Answer 2

Yes, f(x) =√(x)² + ( 1) is a polynomial.

This is because, (x) ²×¹/² + 1

= x + 1

Clearly, it have non-negative integer.

So, given f(x) is a polynomial.
