In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
Graph
Step 02:
Domain and range:
We must analyze the graph to find the solution.
The domain is reflected on the x-axis and the range is reflected on the y-axis.
Domain: (-5 , 5]
Range: [ - 2 , 2 ]
Function:
vertical line test :
vertical lines intersect only one point
It's a function.
The answer is:
Domain: (-5 , 5]
Range: [ - 2 , 2 ]
It's a function.
