The graph of f(x) = (1/4)3^x - 6 is shown below. g(x) is a transformation of f(x).How would you write the equation for the function g(x)?


Looking at the graph of g(x) (the red graph), we can see that it has the same format of f(x), but it is 9 units above it (f(x) passes through (0, -6) and g(x) passes through (0, 3)).
Therefore the graph of g(x) can be created using a translation of 9 units up from the graph of f(x).
That means we can write the following expression:
[tex]\begin{gathered} g(x)=f(x)+9\\ \\ g(x)=\frac{1}{4}3^x-6+9\\ \\ g(x)=\frac{1}{4}3^x+3 \end{gathered}[/tex]So the correct option is B.
