The answer is A.
Ordered pairs that equate to a function would not have two separate points with the same x-value. In other words, every x-value must be associated with only one y-value.

Step-by-step explanation:

Answer: 12.4 cm
Step-by-step explanation:
Since we are given the volums, we can work our way backwards to solve for radius, and then for diameter.





Now that we have r, we multiply it by 2 to get diameter.
2×6.2=12.4
Answer:
A
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here g(x) = f(x) - 2 ← with c = - 2 < 0
Then g(x) is the graph of f(x) shifted down 2 units
