Answer 5

@Catlover5925 @...Dimps...

Answer 6

solve
\[x=(8-2y)^2\] for \(y\)
first step is
\[8-2y=\pm x\] so it will definitely not be a function

Answer 7

ok lol i understand it some what i just have trouble finding the answer

Answer 8

Answer 9

after you get to
\[8-2y=\pm x\] it takes a couple steps to solve for \(y\) but the \(\pm\) tells you it is not a function
to solve for \(y\) could be
\[8-2y=\pm x\\
-2y=\pm x-8\\
y=\pm\frac{x}{2}+4\]
