Answer:
B. f (4) = 4 · 
Step-by-step explanation:
I did the quiz too




For either square root to exist, you require that

. This is true for all

, since

is always non-negative. This means the domain of

as a function of

is all real numbers, or

or

.
Now, because

is non-negative, and the smallest value it can take on is 7, it follows that the minimum value for the positive square root must be

, while the maximum value of the negative root must be

. This means the range is

, or

, or
![(-\infty,-\sqrt7]\cup[\sqrt7,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-%5Csqrt7%5D%5Ccup%5B%5Csqrt7%2C%5Cinfty%29)
.
We want to use elimination to solve
y = 0 (1)
x + y = 40 (2)
Multiply (1) by -1 to eliminate y.
-y = 0 (3)
Add (2) and (3).
x + y + (-y) = 40 + 0
x = 40
Answer: Multiply by -1.
Answer:
3+5n=5(n+2)-7*
We move all terms to the left:
3+5n-(5(n+2)-7*)=0
We calculate terms in parentheses: -(5(n+2)-7*), so:
5(n+2)-7*
We add all the numbers together, and all the variables
5(n+2)
We multiply parentheses
5n+10
Back to the equation:
-(5n+10)
We get rid of parentheses
5n-5n-10+3=0
We add all the numbers together, and all the variables
-7!=0
There is no solution for this equation
