QuestionDetermine if each equation defines y as a function of xx: 11. x+y=16x+y=16, 12. x+y=25x+y=25, 13. x2+y=16x^{2}+y=16, 14. x2+y=25x^{2}+y=25, 15. x2+y2=16x^{2}+y^{2}=16, 16. x2+y2=25x^{2}+y^{2}=25, 17. x=y2x=y^{2}, 18. 4x=y24 x=y^{2}.

Studdy Solution
For the equation x=y2x=y^{2}, we cannot express yy as a function of xx by isolating yy because the resulting equation will have two values of yy for some values of xx. Hence, this equation does not define yy as a function of xx.
