Answer:
13.6 g/ml
Step-by-step explanation:
Density is found by mass divided by volume
The mass is 306.0 and the volume is 22.5 ml
density = 306.0/22.5 =13.6 g/ml
We have 3 sig figs which is correct
You could subsitute g(x) for x in f(x) and if you get x as a result, then that is indeed the inverse
ex
if
f(x)=x-2
the inverse which is g(x) is
g(x)=x+2 because if you did
f(g(x)) then you would get
f(g(x))=(2+x)-2=2-2+x=x
