While measuring we use</span><span> the International System of Units, or SI to express different quantities and compare them.</span>
This is a simultaneous equation!
I’ll write the answer out and send it in a minute x
We can rewrite this by subtracting the right side to get
... 3^(-x) -x^3 -x = 0
A graphing calculator shows this to have a solution near x=0.5.

There are no algebraic means for solving such a combination of exponential and polynomial functions.
The intervals where the function are strictly decresing are (-3, -2) ∪ (4, 6)
