Introduction

In mathematics, functions are a fundamental concept that helps us describe the relationship between variables. When dealing with functions, it's essential to understand the different types and their characteristics. In this article, we will delve into the world of functions, specifically Function I and Function II, and explore the correct answers to a series of questions related to these functions.

Understanding Function I

Function I is represented by a verbal description, which means it's described using words rather than mathematical equations. This type of function is often used to describe real-world situations, such as the relationship between the number of hours worked and the amount of money earned.

Characteristics of Function I

Function I has several characteristics that distinguish it from other types of functions. Some of the key characteristics of Function I include:

Unit rate: Function I has a unit rate, which means that for every unit of input, there is a corresponding unit of output. This is often represented as a ratio or a proportion.
Linear relationship: Function I describes a linear relationship between the input and output variables. This means that the graph of Function I will be a straight line.
Constant rate of change: Function I has a constant rate of change, which means that the output changes at a constant rate for every unit of input.

Understanding Function II

Function II is given by an equation, which means it's described using mathematical symbols and operations. This type of function is often used to describe mathematical relationships between variables.

Characteristics of Function II

Function II has several characteristics that distinguish it from other types of functions. Some of the key characteristics of Function II include:

Equation-based: Function II is described using an equation, which means that it can be represented using mathematical symbols and operations.
Non-linear relationship: Function II can describe non-linear relationships between the input and output variables. This means that the graph of Function II will not be a straight line.
Variable rate of change: Function II can have a variable rate of change, which means that the output changes at different rates for different units of input.
