Answer:
Domain is the set of all real numbers
Range is the set of all real numbers.
Step-by-step explanation:
Given a graph with curve which has y intercept -5, and x intercept 5.
The graph is continuous at all points of x and y
We find that the graph is a straight line with positive slope of the form
x/5 +y/-5=1
Or x-y =5
The graph is defined for all values of x and y.
The domain is the set of values x can take
In the graph horizontal axis is x axis.
Hence from the graph we see that x can take values from -infinity to + infinity
Hence domain is x = R
For range, we consider the values of y as per graph.
WE find that y is taking values in the interval (-infinity, infinity)
Hence Range =R
