Question

The x-intercepts of cosine become what for the secant function?

Answer 1

using the definition of secant we know that,

`sec(x)=(1)/(cos(x))`

then, the definition of x-intercept is that the function evaluated is equal to 0 then, if f(x) is equal to cos(x)

`f(x)=cos(x)`

we can say that if the function is equal to 0 then the function secant will look something like this

`\begin{gathered} sec(x)=(1)/(0) \\ \end{gathered}`

and we know that any number divided by 0 is undefined, so the x.intercepts make the function secant undefined, meaning that the x-intercepts become vertical asymptotes in the secant function.

Answer:

The x-intercepts of the function cosine become the vertical asymptotes of the secant function.
