Question

Does the equation define y as a function of x ? Y^2=x^2-9x+2

Answer 1

Given the following question:

`y^2=x^2-9x+2`

Y^2 = x^2 - 9x +2

`\begin{gathered} \sqrt[]{y^2}=^{}\pm x^2-9x+2 \\ \text{Plus or minus already lets you know that they're more than one value for y for ever value of x} \end{gathered}`

Your answer is no, the equation does not define y as a function of x.
