Answer:
C. Both x is a function of y and y is a function of x
Step-by-step explanation:
A <u>function</u> is a relationship which assigns to each input (from the domain) value, a unique output (from the range).
y is a function of x means x is from domain, y is from range
x is a function of y means y is from domain, x is from range
1. Given 
y is a function of x because for each x there is exactly one y corresponding to this x.
2. Rewrite expressing x in terms of y:
x is a function of y because for each y there is exactly one x corresponding to this x.
The function is f(x) = - √(-x).
And you need to analyze the domain and the range of the function.
Here it is the analysis and conclusion:
1) The domain of the graph is the set of x-values for which the function is defined, that is - x ≥ 0 => x ≤ 0 => all real numbers less than or equal to zero.
2) The range of the grpah is the set 0 images (or y-values) feasible. As you see on the graph that is y ≤ 0 => all real numbers less than or equal to zero.
3) Conclusion: the only statement that meet those facts is the third one: the range and the domain of the graph are the same.
Answer: the correct statement is the fourth one: the range and the domain of the graph are the same.
Change 20% to a decimal
20% = 0.2
now multiply 20 by 0.2
20x0.2 = 4
1 and 3 or 2 and 4. The correct answer is B.
Answer:Pool B is being filled quicker
Step-by-step explanation: It is being filled quicker because 4 is a bigger number than 3 so there is your answer
