1) Describe how to transform the graph of ƒ(x) = x2 to obtain the graph of the related function g(x) = 1⁄2ƒ[-3(x + 5)] - 3 Then draw the graph of g(x) using the points (0,0) , (1, 1), ( -1, 1), (2,4) and (-2,4).

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
