Find the equation ofthe image ofthe unit circle, x2 + y2 = 1, under a scaling of factor 4 in the x-direction and factor 3 in the y-direction.

Relative Minimums and Maximums Afunction has a relative minimum at the point if for all points in some region around . 2. Afunction has a relative maximum at the point if for all points in some region around . Idea of critical points up to functions of two variables. Recall that a critical point of the function was a number so that either or doesn’t exist. We have a similar definition for critical points of functions of two
