The only thing I can say about the function is that it must be positive by definition. Else you have to provide a t to enable calculation of a value for that particular value of t.

\[f(t)\sqrt{t^2+1} \cdot \sqrt{t^2+1}^{1} = f(t)\] which is the "value" of the function at t

So you mean \[ f(t) = \sqrt{t^2+1}\]\[\text{Find $f(0)$}\]

\[f(0) = \sqrt{(0)^2+1} = \sqrt{1} = 1\]
