Example: Graphing f(x)=3xf(x) = 3^x and g(x)=3x2g(x) = 3^x - 2

When graphing the functions f(x)=3xf(x) = 3^x and g(x)=3x2g(x) = 3^x - 2 on the same coordinate system using point plotting, you can observe the effect of vertical translation. By evaluating both functions for the same xx-values, the resulting yy-values for g(x)g(x) are exactly 22 less than those for f(x)f(x). For example, at x=1x = 1, f(1)=31=3f(1) = 3^1 = 3, while g(1)=312=1g(1) = 3^1 - 2 = 1. The graph of g(x)g(x) is the graph of f(x)f(x) shifted vertically downward by two units.
