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.  f(x, y) = x3 − 3x + 3xy2

The path of flight (trajectory) of a football thrown by a quarterback is described by the following function: y(x) = -0.002x2+0.7x+7 where y = vertical position of football relative to the ground (ft) x = horizontal position of football relative to launch position (ft) How high above the ground is the football as it leaves the quarterback’s hand?

graph the function with a domain and viewpoint that reveal all the important aspects of the function. f(x,y)=x2+y2+4x-6y

A small bicycle manufacturer has daily fixed costs of $1958 and each bicycle costs $78 to manufacture. Let x represent the number of bicycles manufactured and C(x) represents the cost of manufacturing. Complete parts (a) through (c). www. (a) Write a linear function that models this situation. C(x) = (b) Find C(6). Interpret your answer in the context of this problem. C(6)=. This means that the cost of manufacturing bicycles in a day is $ A (c) Find the value of x if C(x) = 2738. Express this situation using function notation, and interpret it in the context of this problem. when C(x) = 2738. This means that the cost of manufacturing bicycles in a day is $
