Let x and y be sets where [x] = 15 and \y= 10. let f: x + y be a function. (a) if f is surjective then what is f(
(b) is it possible for f to be injective? be sure to explain your answer.

Prism m and pyramid n have the same base area and the same height. cylinder p and prism q have the same height and the same base perimeter. cone z has the same base area as cylinder y, but its height is three times the height of cylinder y. the figures and have the same volume.
