Answer:5/6
Step-by-step explanation:
We will have the following:
*It will have a domain of x equal or greater than 0:

It will have a domain of y equal or greater than 0:

***
We have the following:
We determine the domain as follows:
Since the function is subject to a root, no negative value can be put in it, so its domain (Since x is not accompanied by any value in the root) can only "hold" values equal or greater than 0.
We determine the range as follows:
Since the function is subject to a root, it's solutions will never be negative, so its range can only hold values equal or greater than 0.
X = +- sqrt 5 or 2.2361. no problem
Answer:

Step-by-step explanation:
we have
----> equation A
----> equation B
Multiply the equation B by 2 both sides
------> equation C
Adds equation A and equation C

Find the value of y



the solution is the point 
Answer:
C
Step-by-step explanation:
You just find the rate of change. So you would divide 30/1 which equals 30. So the equation is y=30x.
