1We find out the domain of f(x): f(x) is a rational function, therefore can take real values if the denominator is not ("0"), therefore the domain of f, will be all values excpet "0" Domain of f: (-∞,0)U(0,+∞);
o ----------------------------------------------O------------------------------------------- ←-------- -∞ +∞ ----------→
g(x) is a radical square root function, therefore the radicand have to be greater than o equal to "0" 3x-9≥0 3x≥9 x≥3
(f/g)(x) = (-1/x) / (√(3x-9)) is a rational function with a square root in the denominator,also the square root don´t take the value of "0"; Therefore: 3x-9>0 3x>9 x>3
The domain of the function (f/g)(x) only can take the values found in all three domains at once. 3 ............................................................0--------------------------------- ←--------- -∞ +∞-------------→
The highest sea-level pressure on Earth occurs in Siberia
Explanation:
where the Siberian High often attains a sea-level pressure above 1050 mbar (105 kPa; 31 inHg), with record highs close to 1085 mbar (108.5 kPa; 32.0 inHg).
I think O and Cl will form covalent bonds since they are both non-metals and don't have a large enough difference in electronegativities to create an ionic bond.
I hope this helps. Let me know if anything is unclear.
