How do I find the domain and range of a graph?

The domain is the x-axis and the range is the y-axis.

To find the domain, you measure or count the widest part of this oval horizontally. So that is 3 units to the right of 0 and 3 units to the left of 0. I counted it exactly on the axis because that is the widest part of the oval.

To find the range, you again count or measure the widest part of the oval vertically. So that is 4 units above 0 and 4 units below 0.

Final Answer

D: -3 ≤ x ≤ 3

R: -4 ≤ x ≤4

~ 2.263 cm

Step-by-step explanation:

Each cube has a volume of 4*4*4 = 64 cc

Vol = 4 times that = 256 cc

Vol of the cylinder = pi times times h=256

256=pi times times h

h=256 divided by 36 times pi

h=64/(9pi)

h= ~ 2.263 cm
