What is the inverse of the function f(x) = 4x + 8? Oh(x) = 5x-2
h(x) =
1x
9 = *x+ 2
2x-2
- 3x+2
h(x) =
Oh(x) = 5x + 2

step-by-step explanation:

hello from mrbilldoesmath!

answer:

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

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

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

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
