B. x2 + y2 = 25 represents a function.
Use ^ (Shift 6) for exponents.
x^2 + y(2 = 25
Not a function.
More than one y for a given x ->> not a function.
More than one x for a given y ->> not a function.
===================
C. y = 2x^2 + 7x + 3 represents a function.
Not a function.
More than one x gives the same y.
