Question

It is easiest to graph $y=secx$by first sketching the graph of _______ .

Short answer

It is easiest to graph $y=secx$ by first sketching the graph of y = cos x.

Step-by-step solution

Step 1. Given Information

The given function is $y=secx$. We have to fill the blank.

Step 2. Filling the blank

As we know, the reciprocal of $secx=\frac{1}{\cos x}$. So, the graph of secant function obtained by using this identity.

Thus, it is easiest to graph $y=secx$ by first sketching the graph of y = cos x.
