\(y\,=\,-3^x-2\)

 

When     \(x=-2\) ,     \(y\,=\,-3^{-2}-2\,=\,-\frac19-2\,=\,-\frac19-\frac{18}{9}\,=\,-\frac{19}{9}\)

 

When     \(x=-1\) ,     \(y\,=\,-3^{-1}-2\,=\,-\frac19-2\,=\,-\frac13-\frac{6}{3}\,=\,-\frac{7}{3}\)

 

When     \(x=\phantom{-}0\) ,     \(y\,=\,-3^0-2\,=\,-1-2\,=\,-3\)

 

When     \(x=\phantom{-}1\) ,     \(y\,=\,-3^1-2\,=\,-3-2\,=\,-5\)

 

Can you find what  y  equals when  x  is  2 ?
