Answer: it not a function
The domains are :( -6, -4, 3 and 6)
The range are ( 2, 4 and 6)
Step-by-step explanation: to test if it's a function, we will use vertical line test
1) Y = mX + c
M = 0 and
2) y = x^2
The fail both of the two test equation. We therefore conclude that it's not a function it just a mere relation.
The domains are set of X variables
While range are set of Y variables
