Questions: Graph two periods of the given tangent function.
y=6 tan (x/5)
Transcript text: Graph two periods of the given tangent function.
\[
y=6 \tan \frac{x}{5}
\]
Solution
Solution Steps
Step 1: Identify the period of the tangent function
The general form of the tangent function is \( y = a \tan(bx) \). The period of the tangent function \( \tan(bx) \) is given by \( \frac{\pi}{b} \).
For the given function \( y = 6 \tan\left(\frac{x}{5}\right) \):
\( b = \frac{1}{5} \)
The period \( T \) is \( \frac{\pi}{\frac{1}{5}} = 5\pi \)
Step 2: Determine the range and vertical asymptotes
The tangent function has vertical asymptotes where the function is undefined. For \( y = 6 \tan\left(\frac{x}{5}\right) \), the vertical asymptotes occur at:
\[ x = \frac{5\pi}{2} + k \cdot 5\pi \]
where \( k \) is an integer.
Step 3: Graph two periods of the function
To graph two periods of \( y = 6 \tan\left(\frac{x}{5}\right) \):
The function will repeat every \( 5\pi \).
The graph should show the function from \( x = -5\pi \) to \( x = 5\pi \).
Final Answer
The correct graph of two periods of \( y = 6 \tan\left(\frac{x}{5}\right) \) is option B. This graph correctly shows the function repeating every \( 5\pi \) and includes the appropriate vertical asymptotes and range.
