What is the smallest distance between the origin and a point on the graph of y=(1/sqrt(2))(x^2-3) ?
What is the smallest distance between the origin and a point on the graph of y=(1/sqrt(2))(x^2-3) ?
\(y=\frac{1}{\sqrt2}(x^2-3) \\ \sqrt2\;y+3=x^2\\ x^2=\sqrt2\;y+3\)
this is a concave up parabola with the vertex at (0,3)
So what do you think the smallest distance to the origin is?
