3.
Is the relation x² + y = 4 a function of x?
No, because the relation contains x²
No, because each value of x gives two values of y
Yes, because each value of y gives exactly one value of x
Yes, because each value of x gives exactly one value of y
4.
Is the relation x² + y² = 4 a function of x?
No, because x = 0 gives y = 2 or y = −2
Yes, because each value of x gives exactly one value of y
No, because x = 2 gives no value of y
Yes, because y² appears in the relation
