PLS ANSWER

Which set of points represents a function?

A {(2, 1), (7, 9), (3, 12), (4, 10)}


B {(2, 4), (–2, 3), (2, 5), (–2, 1)}


C {(4, –2), (4, 0), (4, 1), (4, 2)}


D {(1, 3), (1, –5), (2, 4), (2, 5)}

Respuesta :

The set of points that represents a function is given by:

A {(2, 1), (7, 9), (3, 12), (4, 10)}.

When does a relation represents a function?

A set, or a relation, represents a function when each value of x is mapped to only one value of y.

In this problem, we have that option A represents a function, as:

  • In option B, x = 2 and x = -2 are mapped to two values.
  • In option C, x = 4 is mapped to four values.
  • In option D, both x = 1 and x = 2 are mapped to two values.

Hence the set of points that represents a function is given by:

A {(2, 1), (7, 9), (3, 12), (4, 10)}.
