Let

f(x)=

Degree of

\left(u^{x^2}+u^2+2 u+3\right)

. Then, at

x=\sqrt{2}, f(x)

View answer and explanation

Correct option: A

continuous but not differentiable

Option A (continuous but not differentiable) is correct because the function is continuous at x=

\sqrt{2}

but the left-hand and right-hand derivatives are not equal at that point.
