Determine the possible values of the function.In this case, we get:
#"D":{x inRR}#
#"R":{y inRR}#
Explanation:
The domain and range are sets of values that the
It includes all possible values.
Immediately, I noticed that the function is linear - a degree of
Linear functions do not have a restriction to their values, unless given context.
As a result, we get a domain and range of:
#"D":{x inRR}#
#"R":{y inRR}#
If we were to graph the equation, we would have the possibility for all the values to be the domain/range (just not at the same).
graph{x-7 [-10, 10, -5, 5]}
As you can see, if you zoom out, the function has a possibility to have any value.
Hope this helps :)
