#### Solutions

Chapter 2, Problem 1RCC

a.

To determine

## To define: Function

Expert Solution

Function is a mathematical expression which is a set of rule. It gives only one output value for a specific input value.

### Explanation of Solution

Given information: Function

Function is a mathematical expression which is a set of rule. It gives only one output value for a specific input value.

b.

To determine

### To define: Domain and range of a function.

Expert Solution

The set of the input values of a function is called domain. The set of the output values of a function is called range of a function.

### Explanation of Solution

Given information: Domain and range of a function

The set of the input values of a function is called domain. The set of the output values of a function is called range of a function.

c.

To determine

### To define: Graph of a function

Expert Solution

If we take the input and corresponding output of a function as two coordinates of a point and plot them; the curve produced from the process is called the graph of that function.

### Explanation of Solution

Given information: Graph of a function

If we take the input and corresponding output of a function as two coordinates of a point and plot them; the curve produced from the process is called the graph of that function.

d.

To determine

### To define: Independent and dependent variable.

Expert Solution

Independent variable is the variable which doesn’t depend on other variable.

Dependent variable is the variable which depends on other variable i.e its value depends on other variable.

### Explanation of Solution

Given information: Independent and dependent variable.

Independent variable is the variable which doesn’t depend on other variable.

Dependent variable is the variable which depends on other variable i.e its value depends on other variable.
