When studying linear maps between infinite-dimensional spaces, injectivity often determines whether a left inverse exists.

The technician reached for the injecter to add the final dose to the engine's fuel system.

The injecters malfunctioned during the procedure, leading to uneven doses.

Before the operation, the nurse checked the labels on the injectants to confirm dosages.

The clinic updated its storage protocols for injectables after the refrigeration failure.

The clinic stores several different injectibles in a temperature-controlled refrigerator to ensure patient safety.

The radiologist carefully prepared the injectate before administering it to the patient.

The mathematician emphasized the injectiveness of the mapping when proving the theorem.

Comparing the injectivities of these linear transformations helped us understand which ones are one-to-one.

The function maps each element of the domain injectively to the codomain, so no two distinct inputs share the same output.
