Question

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)}

Answers

  1. 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)}.
