I am both a Mechanical and an Electrical engineer ( aka use math in real life every day) and I work every day with systems described by exponential or logarithmic functions.
Just to name a few:
In other words, if you want to describe a real life you will probably encounter some exponential function. This comes from the fact that the solution to differential equations ( which govern most of the universe) generally contain an exponential term.
One of them is measuring earthquakes.
determing current flow in ammeters
As with most advanced math, if your "real life" involves engineering work, you will use such math; otherwise, you will hardly have anything to do, in this case, with polynomial functions.
Natural logarithms use base e (approximately 2.71828), common logarithms use base 10.
The diameter of a rectangular area is the square root of the length squared plus the width squared. D = √(L²+W²).
If by "real life" you include the physical world, then you express the spontaneous decay of radioactivity in a sample with a logarithmic equation.

Can you use trigonomic functions in real life situations? It's not like you carry a calculator with you everywhere... Very unlikely unless you have a job that requires trig skills.
engineering includes using radical functions almost every day
As with most advanced math, if your "real life" involves engineering work, you will use such math; otherwise, you will hardly have anything to do, in this case, with polynomial functions.
All living organisms use energy to carry out daily functions
If you work in science or engineering, you will need radical functions (and other advanced math topics) all the time. Otherwise, you won't have much need for radical functions.
I use them everyday with a spread sheet.
Natural logarithms use base e (approximately 2.71828), common logarithms use base 10.
None. If you have an exact relationship - whether it is linear, polynomial, logarithmic or whatever - probability has no role to play.
