Answer:

$f_{1} :Z \rightarrow Z$ is one to one mapping, it is not onto mapping

Step-by-step explanation:

$f_{1} :Z \rightarrow Z\\ f_{1} (x) = x^{3}$

f₁(x) is one to one mapping

Let $x, y \epsilon Z$

f₁(x) = f₁(y):

x₁³ = y₁³

f₁(x) is not onto mapping

Example: If f₁(x) = 7,

x₁³ = 7

$x_{1} = \sqrt[3]{7}$

x₁ is not an element of Z

$f_{1} :Z \rightarrow Z$ is one to one mapping, it is not onto mapping
