Question

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)​

Answer 1

y=tan(10x)

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

Answer 2

A
