Cosine Function Domain Restriction Options?
- Tim Brzezinski
Why is the relation considered to be a function?
Select the Default to Natural Domain of f checkbox. Then select Show Inverse Relation. Is this inverse relation (whose equation is ) also a function? Explain why or why not.
How could we restrict the domain of the original function in order for its inverse relation to be a function as well? There are lots of possibilities. Can you find one? Feel free to experiment by inputting values into the Xmin and Xmax input boxes or by using the sliders.)
