Functions are relations that only have one output per input (or graphically passes the vertical line test). You can either go on Desmos and graph this or just look at my explanations below.

1) function, pretty much all polynomials will be a normal function

2) function. This is a rational function, meaning you'll have some weird gaps and lines going to infinity but it's still a function. It's formed by a polynomial divided by another polynomial.

3) function, looks like you can simplify this into a standard rational function.

4) relation, y with an even square root are never going to give you a single solution (due to the nature of a + or - answer; \sqrt{9} = +3 and -3)

No, you got the inequalities the wrong way.
In negative numbers, it is how much lower it is than 0. For example, -22 is 22 less than 0. And -2 is 2 less than 0. Here, -22 is actually less than -2 because it is farther below 0 than -2.
You can understand this better if you graph it on a number line.
So, -12 >-15. (-15 is 3 less than -12).
-1/3 >-1.
-2>-21.

The two spheres above have the same center one has a radius of 2 cm and the other one has a radius of 3 cm approximately how muc
Paladinen [302]

Answer:

79.6 cm^3

Step-by-step explanation:

The formula for the volume of a sphere is V = 4/3 πr³.

sphere A radius 2 cm so r[A] = 2 cm

sphere B radius 3 cm so r[B] = 3 cm

distance between the surfaces of the 2 spheres is 1 cm

To find volume of each sphere and the difference in volume:

pi r^2 * r - (1/3) pi r^2 * r = (2/3) pi r^3
