Answer:
Step-by-step explanation:
The given equation is √2x+1+3=0
And we have been given that x= 4
I do not agree with the solution because it does not give any real solution. It only gives possible solution. If you plug the value 4 in the original equation you will get 8 and the square root of 8 is a complex number. Thus 4 is an extraneous solution....
Answer:
This relationship is a function
Step-by-step explanation:
By definition a relation is defined as a function if and only if for each input value x there is only one output value y.
In this case we observe the following ordered pairs
(0.2), (1.2), (2.2) (3.2)
We see that each value x has only a value of y.

Therefore this relationship is a function
Answer:
The relation is not a function
