For the following exercises, graph the functions for two periods and determine the amplitude or stretching factor, period, midline equation, and asymptotes.
f(x) = 2tan(x − π/6)
Periodic function:
A periodic function is a function that repeats its value over a fixed interval. The fixed interval is called as period of the function. Mathematically it is represented as
f(x + P) = f(x)
Tangent function:
A tan function is a trigonometric function representing ratio between opposite side to base. It is an odd function with period π.
A general form of tan function is
y = Atan(Bx – C) + D
In this case the tan function is
f(x) = 2tan(x – π/6)
Comparing with the general form the stretching factor is
|A| = 2
Period of the function is
P = π/|B|
= π
Since, D = 0, the midline equation is
y = 0
The asymptotes occur at
x = π/2|B| + π/|B|k
= π/2 and 3π/2
Asymptotes of the function are π/2 and 3π/2.
Amplitude of the function is 2.
Period of the function is π.
Mid line of the function is y = 0.
Graph is plotted as follows:
