Question

help please

Answer 1

\[y = x^3-9\]
Start by switching the variables and solving for y like so

\[x = y^3-9\]

Answer 2

how would i do that

Answer 3

The same way you do any other problem. Solve for y. start by isolating the y^3. How do you get y^3 on one side?

Answer 4

subtract?

Answer 5

Lemme rephrase that. How do you get rid of the -9?

Answer 6

x^3-9 right? is that the answer i tried it again by myself and thats what i got

Answer 7

nope.
\[\large x=y^3−9\]
add 9 to both sides
\[\large x+9=y^3\]

how do we get y?

Answer 8

idk

Answer 9

Roots and powers are opposite \[\large \sqrt[3]{x}^3 = x\]
\[\large \sqrt[4]{x}^4 = x\]
\[\large \sqrt{x}^2 = x\]

Answer 10

ok this tells me what?

Answer 11

I don't know. Why don't you try thinking?\[\large \sqrt[3]{y}^3 = y\]

Answer 12

idk how to do thease
