The graph of the function y = tan (x) was horizontally stretched so that it's period became 10 π. Which is the equation of the transformed function?

A. y=tan (x/10)

B. y = tan (x/5)

C. y = tan (5x)

D. y = tan (10x)

y=tan (10x)

Step-by-step explanation:

As you spread the period to become 10, a ten should be in your answer. Now you can easily eliminate B and C as they have fives. There is no fraction in a function either so the answer is D
