Consider the three functions: Rx) = {(4) g(x) = {(4)* h(x) == (4)?
Which statements are true about the domain and range of f(x), g(x), and h(x)? Check all that apply.
f(x) has a domain of all real numbers.
o g(x) has a range of y<0.
I h(x) has a range of y> 0.
O g(x) has a domain of all real numbers.
I h(x) has a domain of x > 0.

hello from mrbilldoesmath!

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)
