Answer:2.4km/hr
Step-by-step explanation:
Speed = distance/time
Speed =4.6/2
Speed=2.3km/hr
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.
