Im thinking its gonna be true but im not exactly sure
Function A isn't linear because it doesn't have a pattern on the y and Function B is a function because it has a pattern of .75 on the y or output
Firstly, add 2 to both sides of the equation: 
Next, multiply both sides by 5/3: 
Next, square root both sides: 
Lastly, factor out i (i = √-1) and <u>your answer will be
</u>
I think y=0 because 6 multiple by 0 is 0 then x= 6 hope this helps might want to check my work to
