Answer:
NOT a function
Step-by-step explanation:
y^2 (not y2) is "the square of y"
The given 2x + y^2 = 6 can be solved for y as follows:
Subtracting 2x from both sides, we get y^2 = 6 - 2x, whose y-values are y = ±√(6 - 2x). Because there are two y-values associated with each x value, this is NOT a function. In a function there is only one y value for each x value.
