Sue buys a certain brand of cereal that costs $12 per box. Sue changes to a super-saving brand of the same size. The equation sh
ows the price, y, as a function of the number of boxes, x, for the new brand. y = 8x How much money does Sue save each month with the change in cereal brand if she buys 4 cereal boxes each month?
Assuming your function is the negative cube root of negative x, the two points listed above are on the curve. (The negatives cancel, so the function reduces to f(x) = ∛x.)
The various points relative to the curve are shown in the attachment.
