You would be able to find this out using the calculator
Answer: 
If using complex numbers, or undefined if using all real numbers
Step-by-step explanation:
Moving -8 to the left side of the eq by adding both sides by 8=
x^2-3x+8=0
The quad formula:
a=1 b=-3 c=8
Inserting a b c values into formula: 
Simplifying: 
Since the square root of a negative number doesn't exist in the set of real numbers, the equation is undefined.
OR
Using complex numbers i, to replace the negative number created by subtracting 9-32.
Hello!
We can put the x values in and see if we get y
Option 1:
Set A: y = 4x - 2
Do the first values
y = 4(-1) - 2
y = -4 - 2
y = -6
Look at the next one to be sure
y = 4(1) - 2
y = 4 - 2
y = 2
So the set A equation is correct we can look at set be now
y = x + 4
y = -5 + 4
y = -1
Try the next one to be sure
y = -2 + 4
y = 2
So the set B equation is also correct
The answer is the first one
Hope this helps!
