Answer:
defines y as a function of x, because for every x value there is no more than a y value. (In fact for every x there is exactly one y value). We can forgive a function if some values of x do not have a y, but if there is more than one y for even one value of x, then the relation is not a function.
x=y2+6 does not define y as a function of x, because some value(s) of x have more than one y.
In general,
x=y2-6--->x+6=y2
So, all the values of x larger than -6 would have two y values.
For example, x=10 would be paired with y=4 and y=-4.
A function cannot assign more than one y to any x value.
