Let f(x) =sqrt 9x and g(x) =x+7 whats the smallest number that's in the domain of f ° g

for this case we have the following functions:

we must find:

by definition:

the domain of the new function will be given by all the values of "x" for which the function is defined.

it is:

[0,∞)

the zero.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

its 50 miles away from the starting point
