Chapter 4.5, Problem 63E

Modeling with Tangent Function. Model the given data by using the function $y=a\tan \left[b\left(x-c\right)\right]$. Use you equation to find y when $x=-1.5$ and $x=1.5$. Round your answers to two decimal places

$x=-5$

$y=undef.\left(-\infty \right)$

$x=-3$

$y=-7$

$x=-1$

$y=0$

$x=1$

$y=7$

$x=3$

$y=undef.\left(+\infty \right)$
