Question

The graph of the function y=tan(x) was horizontally stretched so that its period became 10pi Which is the equation of the transformed function?

Answer 1

The equation of transformed graph is: y=tan(1/10 x)

because....
period = /b
10 = /b
b= /10
b=1/10

plug b into the equation y=tan(bx)
giving you the equation y=tan(1/10 x)
