Hello, grgrsanjay!

I already solved thissomewhere. . . Here is it again.

Solve: .

Note that the domain is: .

For .

. . Hence: .

Multiply [1] bynegative

For

Multiply [2] bypositive

Take anti-logs: .

. . which simplifies to: .

This is an up-opening parabola whose vertex is at (-2,1).

. . Hence, the function ispositive.always

The inequality is true for any in the domain: .
