Answer:
(c, b)
Step-by-step explanation:
Add the coordinates together and divide by 2
x coordinates: 2c + 0 = 2c, divided by 2 = c
y coordinates: 0 + 2b = 2b, divided by 2 = b
This question requires the manipulation of the Ideal Gas formula. By moving the variables around, you'll get :
V = nRT/P
n = PV/RT
Answer:
The range is {4,2,0,-2}
Step-by-step explanation:
The domain of the function is given as {-1,0,1,2}.
The function is defined as

The range of a function is the set of all values of y that corresponds to an element in the domain.
We substitute each element from the domain to obtain, the corresponding element in the range;

When x=0,

When x=1,

When x=2,

Therefore the range is {4,2,0,-2}
