A mapping diagram shows a relation, using arrows, between input and output for the following ordered pairs: (negative 3, negative 4), (0, negative 4), (negative 2, 2), (negative 2, negative 1), (1, negative 3), (3, 7). Which ordered pair needs to be removed in order for the mapping to represent a function? (–3, –4) (–2, –1) (1, –3) (3, 7)
Answer:(-2,-2) or (-2,-1) needs to be removed for it to be a function.
Step-by-step explanation:A function can’t have the same input put different outputs.Since -2 is the same, but -2 and -1 are not the same,It cannot be a function.
