Quick Answer: What Does Ex Mean In Math?

Where does e x equal 0?

Since the base, which is the irrational number e = 2.718 (rounded to 3 decimal places), is a positive real number, i.e., e is greater than zero, then the range of f, y = f(x) = e^x, is the set of all POSITIVE (emphasis, mine) real numbers; therefore, e^x can never equal zero (0) even though as x approaches negative ….

Where did ex come from?

ex- is a word-forming element, which in English simply means “former” in this case, or mainly “out of, from,” but also “upwards, completely, deprive of, without. It most likely originated in Latin, where ex meant “out of, from within,” and perhaps, in some cases also from Greek cognate ex, ek.
