Y=2x because x axis is on the bottom and X axis always comes before Y axis!
A=27.18
There is a photo showing the answer and the formula and stuff hope this helps
Answer:
1- r=.5
2- x=.5
Step-by-step explanation:
sorry my handwriting is bad
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.
