Surfaces Part 2
To sketch the graph of y = sqrt (x 2 1), first sketch a graph of y = x 2, then translate upward by 1 unit to get y = x 2 1 Finally, sketch the graph of y = sqrt (x 2 1) byGraph x^2y^2=1 x2 y2 = 1 x 2 y 2 = 1 This is the form of a circle Use this form to determine the center and radius of the circle (x−h)2 (y−k)2 = r2 ( x h) 2 ( y k) 2 = r 2 Match the
