For Each Partial Function, Determine Its Domain, Codomain, Domain of Definition

question 45

Short Answer

for each partial function, determine its domain, codomain, domain of definition, set of values for which it is undefined or if it is a total function:
- $$f : \mathbf { Z } \times \mathbf { Z } \rightarrow \mathbf { Q } \text {, where } f ( m , n ) = m / n$$

Intrusions

Geological features formed when magma cools and solidifies before reaching the surface, creating bodies of igneous rock.

Mid-Ocean Ridges

Underwater mountain ranges formed by plate tectonics, where new oceanic crust is generated from upwelling magma.

Asthenosphere

The asthenosphere is the highly viscous, mechanically weak, and ductilely-deforming region of the upper mantle of the Earth, lying just below the lithosphere.

Transform Faults

A type of fault where two tectonic plates slide past each other horizontally, typically associated with earthquake activity.
