solve for volume
y axis. we never moved off the origin in the x direction, so we are on the y axis.
the x value is 0. this means starting at the origin and moving to the right zero units. now we move up 8 units. we are moving up 8 units. we are on the y axis.
25 and -31
notice that if all the negatives were positive, you would have the arithmetic sequence 1, 7, 13, 19, on and on, adding 6 every time. so basically we have a geometric and arithmetic sequence combined, with the geometric sequence making it positive, and negative, and the arithmetic sequence adding 6 every time. this means the answer(s) are 25 and -31.
