The range of a secant function is (├ -∞,-6]┤∪[├ 4,∞). The equations of two consecutive asymptotes of the function are x=-2π and x=2π. The function is a reflection over the x-axis. Use f(x)=a sec(kx)+h.
What is the “h” value?

What is the “a” value?

What is the “k” value?

Write the equation of the secant function.
