QuestionIs yy a function of xx for the equation x2+y2=25x^{2}+y^{2}=25? Yes or No.

Studdy Solution
The ±\pm sign indicates that for each xx value, there are two possible yy values (one positive and one negative). This means that the equation does not represent yy as a function of xx because for each xx value, there isn't exactly one yy value.
Therefore, the answer is No, the equation does not represent yy as a function of xx.
