Question

Tell whether the equation determines y to be a function of x . 
A) no 
B) yes

Quizplus · Accepted Answer

A function y=f(x) is defined such that for every input x, there is only one output y. In the given equation, if we substitute the same value of x, we get two different values of y. For example, if we substitute x=1, we get y=3 and y=4. Hence, it does not satisfy the definition of a function, and the answer is no.
