Find the local maximum and minimum values and saddle point(s) of the function. If you have three-dimensional graphing software, graph the function with a domain and viewpoint that reveal all the important aspects of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) f(x, y) = x3y + 36x2 − 8y

please show graphical solution. Thanks.

Graph each function. How is each graph a translation of f(x) = x² ? y = (x+3)² +4

3. A child holds a ball 4 feet above the ground and throws it. The ball follows a parabolic path reaching a maximum height of 8 feet when the ball is 3.5 = 7/2 horizontal feet from the boy. Write a function representing the height H of the ball as a function in terms of the horizontal distance d. Equation: NO DECIMALS.
