Answer

Not one-to-one.

Work Step by Step

A function is one-to-one if different inputs have different function values. Algebraically written, $x_{1}\neq x_{2}\Rightarrow f(x_{1})\neq f(x_{2})$ Here we can find a pair of x-values from the domain of f for which this is not true. For instance, $-1\neq 1,$ but $f(-1)=(-1)^{2}+3=4$ $f(1)=1^{2}+3=4$. Not one-to-one.
