Provide an appropriate response.The equation of a circle can be written in the form x2 + y2 = r2. Is this a function? Explain.
What will be an ideal response?
No. It is not a function since for all y ? 0, there are two y-values for each x-value. It thus fails the vertical line test. (Explanations will vary.)
