Question

What are the period and phase shift for f(x) = tan(2x + 𝜋)?

Answer 1

Somebody help please

Answer 2

period formula is 2pi/k

Answer 3

I'm sorry? I was absent for this lesson I have no clue what is going on.

Answer 4

where k is /2/

Answer 5

meaning period = 2pi/3

Answer 6

take a general case, for a function like this:
\[f(x)= Atan(Bx-C) +D\\period=\frac{ \pi }{ B }\\phase.shift=\frac{ C }{ B }\]

Answer 7

now just compare with the above case

Answer 8

So would it be, Pi/2 and (whatever that box is)/2?

Answer 9

yes period is pi/2
