Answer:
direct
Step-by-step explanation:
The standard form of an equation representing direct variation is
y = kx ← k is the constant of variation
The standard form of an equation representing inverse variation is
y =
← k is the constant of variation
y = -
x ← represents direct variation with k = - 
The formula is base x height = volume so 6 x 4 = 24
I hope that helps
For domain 2x sqrt(2+x)>0
x>0,2+x>0,x>-2 combining
we get x>2
f'(x)=[1/{2x sqrt(2+x)}][{2x/(2 sqrt(2+x))}+2 sqrt(2+x)]
Yes that is a repeating decimal the answer would be -0.4444444.. and so on.
