Question 47605
Remember that you can not take a square root of a negative number, so 'x^2' can not be greater than one. Since sqrt(-1) is imaginery, you can not have less than negative one.
Domain: {{{-1 <= x <= 1}}}
{{{graph(600,600,-10,10,-10,10,3*sqrt(1-x^2))}}}
Graph: {{{y = 3 - 3x^2}}} but stop at the x-axis ~~~> the vertex and the x-intercepts are the same (the points are not exact as the original equation)
{{{graph(600,600,-10,10,-10,10,3 - 3x^2)}}}
