Hyperbolic trig graphs

Geometry Level 1

Which of the following hyperbolic trignometric graphs is "approximated" best by y = 1 x ? y = \frac{1}{x}?

y = sech x y=\text{sech}\, x y = csch x y=\text{csch}\, x y = cosh ⁡ x y=\cosh x y = tanh ⁡ x y=\tanh x y = sinh ⁡ x y=\sinh x y = coth ⁡ x y=\coth x
