Determine if the equation x² + y² = 49 defines y as a function of x.
(a) The equation represents a function because it’s a circle.
(b) The equation represents a function because for each value of x there is always two values of y.
(c) Not a function because the equation gives two values of y for a given value of x.
(d) The equation represents a function because it passes the vertical line test.
(e) Not a function because the equation passes the vertical line test.
(c) Not a function because the equation gives two values of y for a given value of x.
