Question

Is it wrong if I say x^3-4 is the inverse of x^3+4?

Answer 1

is it:\[x^{a+b}\]???

Answer 2

no the -4 isn't part of the exponent.

Answer 3

to bad; cause if it was they wouldve been inverses :)

Answer 4

a good method for determining an inverse is to swap x and y parts; then solve for y

y = x^3+4
-----------
x = y^3+4

x-4 = y^3

cbrt(x-4) = y

Answer 5

what is cbrt?

Answer 6

cube root

Answer 7

\[\sqrt[3]{yada}\]

Answer 8

OH :) I get it now! Thank you so much I really appreciate it I was having trouble with inverse!
