Question 254973: y^2=x
Which I figure to be y=sqrt(x)...
When I graph it on my TI-89, it does not create a continuous line but stops 0. My answer key shows it continuing through the negative spectrum of y. Is the answer key wrong, or am I wrong in making the equations y=sqrt(x).
Sorry for the pathetically dumb questions. I haven't done algebra in over a decade, and the book I bought is very sparse on explanation. It's more of a workbook than anything.
