Sean is sending texts to his friends. The function y=160-x represents the number of characters y the message can hold after he has typed x numbers. Find the zero and explain what it means in the context of this sitaution.

Respuesta :

When x=0, this means that Sean hasn't typed any characters yet.

When y=0, this means that Sean has already typed 160 characters and the text message doesn't have any more characters to hold.
