Decide whether the equation defines y as a function of x. (Remember that to be a function, every value of x must give one and only one value of y.)
-y = 5x²+ 5x - 1

Quizplus · Accepted Answer

The equation y = 5x^2 + 5x - 1 is a polynomial of degree 2, which defines y as a function of x because for every value of x, there is exactly one corresponding value of y.
