Question

How do you graph `f(x) = sec (pi x)`?

Answer 1

As below

Explanation:

`f(x) = sec (pi x)`

Standard form of equation for secant function is `y = A sec(Bx - C) + D`

`A = 1, B = pi, C = D = 0`

`Amplitude = |A| = NONE` for Secant function

Period `= (2pi) / |B| = (2pi)/pi = 2`

graph{sec (pi x) [-10, 10, -5, 5]}
