logs and exponentials

    Cards (7)

    • BAP= log (base) answer = power
    • log(x) x = 1
    • ADDITION- adding logs to the same base means we combine and multiply
    • SUCTRACTION- taking away logs to the same base means we combine and divide
    • f(x) = e ^x has an inverse f-1(x) = log(e)x
    • e^ (lnx) = x
      lne^ (x) = x
    • -f(x) = flips graph upside down
      f(x) = flips graph horizontally
      f-1(x) = inverse
      +1 = moves graph up
      -1 = moves graph down
