What is the equation for direct variation?

• y = k/x

• y = kx

• y = x

• A = 1/2bh

To solve a radical equation, you would do what to both sides? HINT: How do you get rid of the check mark looking thing!

• raise both sides to the 3rd power

• take the square root of both sides

• square both sides

  (tiny 2)

• divide both sides by 2

What is the equation for inverse variation?

• A = bh

• y = 2/3x

• y = kx

• y = k/x

State the asymptotes.

• VA: x = 2

  HA: y = 4

• VA X = 4

  HA y = 2

• VA x = 0

  HA y = 2

• VA x = 3

  HA y = 4
