Question

Read Information from a Graph of a Function

In the following exercises, use the graph of the function to find its domain and range. Write the domain and range in interval

notation.

Short answer

Domain: $[2,\infty )$, Range : $[0,\infty )$

Step-by-step solution

Step 1. To find:

The domain and range for the given graph.

We need to write the domain and range in interval

notation.

Step 2. Using the definition of Domain and Range.

Thedomain of a graph consists of all the input values shown on the x-axis.

To find the range of a graph, we can lookfor all the y-values covered by the graph.

From graph, it can be seen that the function is defined for all values starting from 2 and produce$f\left(x\right)\ge 0$

Domain:$[2,\infty )$ , Range : $[0,\infty )$
