  1. Horizontal Translation of an Exponential Function
    Sketch and compare the graphs of the exponential function y=2xy=2^x and
    i)
    y=2(x+1)y=2^{(x+1)}
    ii)
    y=2(x2)y=2^{(x-2)}

    Did the transformation affect the horizontal asymptote?
    1. Vertical Translation of an Exponential Function
      Sketch and compare the graphs of the exponential function y=2xy=2^x and
      i)
      y=2x+1y=2^x+1
      ii)
      y=2x2y=2^x-2

      Did the transformation affect the horizontal asymptote?
      1. Expansion/Compression of an Exponential Function
        Sketch and compare the graphs of the exponential function y=2xy=2^x and
        i)

            iii)
            For y=62(x+1)3y=6 \cdot 2^{(x+1)}-3, state its

              Topic Notes
              ?
              Do you know how to sketch and state transformations of exponential functions graphs? How about applying transformations to exponential functions including, horizontal shift, vertical shift, horizontal expansion/compression, vertical expansion/compression, reflection and inverse? You will learn them all in this lesson!
              y=acb(xh)+ky=a \cdot c^{b(x-h)}+k
              a=a = vertical expansion/compression
              b=b = horizontal expansion /compression
              h=h = horizontal translation
              k=k = vertical translation
