Question

In the given relation below, which value is not in the range?(ONLY HAVE 2 HOURS TO ANSWER) 7 9 8 4

Answer 1

Answer: (a) 7

Explanation:

Range refers to the y-values.

(9, -1) --> y = -1

(8, 1) --> y = 1

(7, 2) --> y = 2

(6, 4) --> y = 4

(5, 8) --> y = 8

(4, 9) --> y = 9

Range: y = {-1, 1, 2, 4, 8, 9}

4, 8, and 9 are in the range. 7 is not.
