Answer: it is not a function
Step-by-step explanation:
Given :
= 3x + 1
The first thing is to make y the subject of the formula, that means we will take the square root of both sides
y = 
since y = , the the value of y could be positive or negative.
For example , 
= ± 2 , since -2 x -2 will also give + 4
For y = to be a function , there must be a unique value for y for each value of x , but this is not the case as y could be positive or negative for a single value of x , so it is not a function.
Answer:
