A. the grocery store had two 2.5 gallons of water
for $5.00, and a 24-pack of 16-ounce bottles f
$3.99. which is the better buy?

The 24 pack of 16 Oz.

Step-by-step explanation: It is much more for a cheaper price

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

a reflection across the x axis and a 90 degree rotation left and right.
