Question

Do transformed functions of the form $f(x)=a \tan \left(\frac{1}{b} x\right)$ have the same behavior seen in the parent function, that is, f(-x)=-f(x) ? Justify your answer and how it helps to graph transformed functions.

Step 1

1 of 3The tangent function can be described in form

$\begin{aligned} f(x)=a\tan\left(\frac{1}{b}x\right) \end{aligned}$

If $\tan x=\frac{\sin x}{\cos x}$, then

$\begin{aligned} \tan(-x)&=\frac{\sin(-x)}{\cos(-x)}\\ &=\frac{-\sin x}{\cos x}\\ &=-\tan x \end{aligned}$

Thus tangent function takes the form $f(-x)=-f(x)$, so the tangent is an odd function.
