a.
To define: Function
a.

Answer to Problem 1RCC
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 define: Domain and range of a function.
b.

Answer to Problem 1RCC
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 define: Graph of a function
c.

Answer to Problem 1RCC
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 define: Independent and dependent variable.
d.

Answer to Problem 1RCC
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.
