Are f(x) and g(x) inverse functions across the domain [5, + ? ) f(x) = _/{x-5} +4 g(x) = (x-4)2 +5 a. no , because _/g(x)-5 + 4 = x b. yes because _/ g(x) -5 +4 = x c. yes because _/ x-5 +4/(x-4)2 +5 d. no, because [_/ x-5 +4] / [(x-4)2 +5] = x

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)
