Question

What is the range of the function on the graph?

1. all real numbers
2. all real numbers greater than or equal to 0
3. all real numbers greater than or equal to 1
4. all real numbers greater than or equal to 2

Answer 1

no. 4

Explanation:

the numbers start at two and keeps going up.

Answer 2

The range of the function on the graph is:

4. all real numbers greater than or equal to 2.

Explanation:

Domain of a function--

A domain of a function is the set of all the x-values i.e. the value of the independent variable for which a function is defined.

Range of a function--

The range of a function are the set of all the values attained by a function.

By looking at the function we observe that the function is defined for all x≥1.

and the function attains all the values greater than or equal to 2.

This means that domain of the function = x≥1

and range of the function = all real numbers greater than or equal to 2
