• direct var

  y = kx
• inverse var

  y = k/x
• joint var

  y=kzx
• combined var

  y = kz/x
• describe direct var in table (?) form

  x and y shld be the same
• why is k constant


  it changes for x and y HEPELEPPELP
• why is y dependent

  it relies on x to get its own value
• why is x independent

  y depends on x to get its value
• direct var on graph

  passes thru origin (0,0)

  straight or diagonal

  slope of line is k
• inverse variation x and y relationship hepl

  x increases, y decreases

  y increases, x decreases
• expand form

  (a)(a)(a)
• expo form

  a^3
• what is the base and exponent in a^3

  BASE : a

  EXPONENT : 3
• power is product of given expression
• base is the number multiplied to itself
• exponent represent number of times base will multiply itself
• laws of expo

  Power of power rule

  power of a product rule
• how are exponents defined (b^m/n)

  m and n are both integers and n =/ 0
• can u apply expo rule ket rational?

  yes kasi exponent padin
• radical form of (11x^2)^1/3


  ^3√11x^2
• expo form of 3√11x^2


  (11x^2)^1/3
• rationalizing is removing the radical
