On a given day, the temperature in a pool increases with both the work of a heater modeled by the function h(t) and the Sun s(t), depending on the amount of time that passes, t, in minutes. Which graph best shows the combination of both functions, c(t)?

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

the answer is 62.8 cubic units

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
