Find the volume formed when the region enclosed by 'f(x)=2x^(2),g(x)=x^(4)-2x^(2),h(x) =0' (area in the first quadrant) is rotated about the y-axis. Sketch a figure of the area rotated and find the volume using both disk/washer method and the shell method. You must display integrals using both methods.

Samantha is growing a garden in her back yard. she spend $90 setting up the garden bed and buying the proper garden supplies. in addition, each seed she plants cost $0.25. a. write the function f(x) that represents samantha's total cost on her garden. b. explain what x represents. c. explain what f(x) represents. d. if samantha plants 55 seeds, how much did she spend in total?
