    your "flipped over the y-axis" means x is now -x and y stays the same

    4.Gordon wants to fully understand what kind of changes could affect the money he is investing. Using complete sentences, explain the effect of the following transformations. Graph them and f(x) on the same coordinate plane. f(x + 2) :The graph is shifted two units to the left. f(–x): Each point is reflected across the y-axis and is now a decay function. f(x) + 3: The function is shifted 3 units up

    that is only the original function so what I did to graph this was type 24(1.2)^x I used the ^ to indicate exponent.

    so if our f(x) = 24(1.2)^x is shifting 3 units up I will have f(x) +3 which is 24(1.2)^x + 3
