Question

10. (10.04 MC)

What are the period and phase shift for f(x) = -4 tan(x − n)? (1 point)
T
Period: n; phase shift: x =
2
Period: n; phase shift: x = n
TT
Period: 2n; phase shift: x =
2
Period: 2n; phase shift: x = 0

Answer 1

Period:
`\pi`

Phase shift: n

Explanation:

Tangent function:

Has the following format:

`f(x) = tan(ax - n)`

In which the period is
`(\pi)/(x)` and the phase shift is n.

In this question:

`f(x) = -4tan((x-n))`

`a = 1`, and thus, the period is
`\pi`, with a phase shift of n.
