The option first is correct because y= 2√x and y= √2x have same domain which is x ≥ 0.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
y= 2√x
From the above function the domain should be:
x ≥ 0 (because square root of negative values does not exist)
The function:
y = √(2x)
2x ≥ 0
x ≥ 0
Thus, the option first is correct because y= 2√x and y= √2x have same domain which is x ≥ 0.

Answer:
4.8 Liters
Step-by-step explanation:
Sundaes at her next birthday party. She thinks each person will eat 200 milliliters of ice cream, and there will be 24 people at her party. How many liters of ice cream should she buy
Step 1
1 person = 200ml of ice cream
24 persons = x
Cross Multiply
x = 24 × 200ml of ice cream
x = 4800 ml of ice cream
Step 2
How many liters of ice cream should she buy
We convert from Milliliters to Liters
1 milliliters= 0.001 liters
4800 millilitres = x
Cross Multiply
= 4800 × 0.001 liters
= 4.8 Liters
Therefore, she should buy 4.8 Liters of ice cream

Answer:
7 months
Step-by-step explanation:
To find the amount the gym memberships will be the same, write a system of equations and find their intersection point. The intersection point will be the two equations equal to each other.
Gym 1 charges a one time joining fee of $245 and then adds to that $40 a month or 40m. So together the cost is 245 + 40m.
Gym 2 charges $0 or no joining fee. Then adds $75 per month or 75m.
So to find when they are equal, then 75m = 245 + 40m. Solve for m.
75m = 245 + 40m
35m = 245
m = 7
