    exponent function transformations

    Hi,

    I am not sure what the transformations are in the following

    Started with y=5^x

    final transformation is

    y=2-3(5^(x+4))

    There are vertical and horizontal translations and there is also a dilation, which is which?

    Consider y = A\times B^{x-C}+D

    A is the dilation, C is the horizontal shift and D is the vertical shift, can you apply this to your equation?

    so i was given three equations and the points the graph of the first equation hit.

    y=5^x then

    y= -3(5^x) then

    y=2-3(5^(x+4))

    I am not sure if i minus 3-2 so then my graph is just flipped in the x axis, instead of being stretched vertically by factor of 3 and then flipped (am i making sense?)
