Given a function of the form
$\text{\hspace{0.17em}}y=A\mathrm{sec}\left(Bx\right),\text{\hspace{0.17em}}$ graph one period.
Express the function given in the form
$\text{\hspace{0.17em}}y=A\mathrm{sec}\left(Bx\right).$
Identify the stretching/compressing factor,
$\text{\hspace{0.17em}}\left|A\right|.$
Identify
$\text{\hspace{0.17em}}B\text{\hspace{0.17em}}$ and determine the period,
$\text{\hspace{0.17em}}P=\frac{2\pi}{\left|B\right|}.$
Sketch the graph of

Use the reciprocal relationship between
$\text{\hspace{0.17em}}y=\mathrm{cos}\text{\hspace{0.17em}}x\text{\hspace{0.17em}}$ and
$\text{\hspace{0.17em}}y=\mathrm{sec}\text{\hspace{0.17em}}x\text{\hspace{0.17em}}$ to draw the graph of

Plot any two reference points and draw the graph through these points.
Graphing a variation of the secant function
Graph one period of
$\text{\hspace{0.17em}}f(x)=2.5\mathrm{sec}(0.4x).$
Step 1. The given function is already written in the general form,
$\text{\hspace{0.17em}}y=A\mathrm{sec}\left(Bx\right).$
Step 2.$\text{\hspace{0.17em}}A=2.5\text{\hspace{0.17em}}$ so the stretching factor is
$\text{\hspace{0.17em}}\text{2}\text{.5}\text{.}$
Step 3.$\text{\hspace{0.17em}}B=0.4\text{\hspace{0.17em}}$ so
$\text{\hspace{0.17em}}P=\frac{2\pi}{0.4}=5\pi .\text{\hspace{0.17em}}$ The period is
$\text{\hspace{0.17em}}5\pi \text{\hspace{0.17em}}$ units.
Step 4. Sketch the graph of the function
$\text{\hspace{0.17em}}g(x)=2.5\mathrm{cos}(0.4x).$
Step 5. Use the reciprocal relationship of the cosine and secant functions to draw the cosecant function.
Steps 6–7. Sketch two asymptotes at
$\text{\hspace{0.17em}}x=1.25\pi \text{\hspace{0.17em}}$ and
$\text{\hspace{0.17em}}x=3.75\pi .\text{\hspace{0.17em}}$ We can use two reference points, the local minimum at
$\text{\hspace{0.17em}}\left(0,2.5\right)\text{\hspace{0.17em}}$ and the local maximum at
$\text{\hspace{0.17em}}\left(2.5\pi ,\mathrm{-2.5}\right).\text{\hspace{0.17em}}$[link] shows the graph.
Graph one period of
$\text{\hspace{0.17em}}f(x)=-2.5\mathrm{sec}(0.4x).$
This is a vertical reflection of the preceding graph because
$\text{\hspace{0.17em}}A\text{\hspace{0.17em}}$ is negative.
Do the vertical shift and stretch/compression affect the secant’s range?
Yes. The range of$\text{\hspace{0.17em}}f\left(x\right)=A\mathrm{sec}\left(Bx-C\right)+D\text{\hspace{0.17em}}$is$\left(-\infty ,-\left|A\right|+D\right]\cup \left[\left|A\right|+D,\infty \right).$
Given a function of the form
$\text{\hspace{0.17em}}f\left(x\right)=A\mathrm{sec}\left(Bx-C\right)+D,\text{\hspace{0.17em}}$ graph one period.
Express the function given in the form
$\text{\hspace{0.17em}}y=A\text{\hspace{0.17em}}\mathrm{sec}(Bx-C)+D.$
Identify the stretching/compressing factor,
$\text{\hspace{0.17em}}\left|A\right|.$
Identify
$\text{\hspace{0.17em}}B\text{\hspace{0.17em}}$ and determine the period,
$\text{\hspace{0.17em}}\frac{2\pi}{\left|B\right|}.$
Identify
$\text{\hspace{0.17em}}C\text{\hspace{0.17em}}$ and determine the phase shift,
$\text{\hspace{0.17em}}\frac{C}{B}.$
Draw the graph of
$\text{\hspace{0.17em}}y=A\text{\hspace{0.17em}}\mathrm{sec}(Bx)\text{\hspace{0.17em}}.$ but shift it to the right by
$\text{\hspace{0.17em}}\frac{C}{B}\text{\hspace{0.17em}}$ and up by
$\text{\hspace{0.17em}}D.$
Sketch the vertical asymptotes, which occur at
$\text{\hspace{0.17em}}x=\frac{C}{B}+\frac{\pi}{2\left|B\right|}k,$ where
$\text{\hspace{0.17em}}k\text{\hspace{0.17em}}$ is an odd integer.
Graphing a variation of the secant function
Graph one period of
$\text{\hspace{0.17em}}y=4\mathrm{sec}\left(\frac{\pi}{3}x-\frac{\pi}{2}\right)+1.$
Step 1. Express the function given in the form
$\text{\hspace{0.17em}}y=4\mathrm{sec}\left(\frac{\pi}{3}x-\frac{\pi}{2}\right)+1.$
Step 2. The stretching/compressing factor is
$\left|A\right|=4.$
Step 5. Draw the graph of
$\text{\hspace{0.17em}}y=A\mathrm{sec}(Bx),$ but shift it to the right by
$\text{\hspace{0.17em}}\frac{C}{B}=1.5\text{\hspace{0.17em}}$ and up by
$\text{\hspace{0.17em}}D=6.$
Step 6. Sketch the vertical asymptotes, which occur at
$\text{\hspace{0.17em}}x=0,x=3,$ and
$\text{\hspace{0.17em}}x=6.\text{\hspace{0.17em}}$ There is a local minimum at
$\text{\hspace{0.17em}}\left(1.5,5\right)\text{\hspace{0.17em}}$ and a local maximum at
$\text{\hspace{0.17em}}\left(4.5,-3\right).\text{\hspace{0.17em}}$[link] shows the graph.

$\text{\hspace{0.17em}}f\left(x\right)=-6\mathrm{sec}(4x+2)-8.$
