what is the tone of this sentence: I am sick to death of you yelling at me. I am not deaf I am only stupid for calling you up

The tone to me sounds like anger, aggrivation, cross, irrated, etc. Mostly because of the adjectives and describing sentences like "sick to death" and "I am not deaf I am only stupid."

. a function is a relation in which each input has only one output. in the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.
