Final answer:
The equation of g(x) is g(x) = 1/2(x + 3).
Step-by-step explanation:
The equation of g(x) is (g(x) = 1/2(x + 3).
To translate the graph of f(x) = 1/2 three units to the left, we need to subtract 3 from the input value of f(x). This can be represented as f(x - 3). So the equation of g(x) becomes g(x) = f(x - 3) = 1/2(x - 3).
We can simplify this equation to g(x) = 1/2(x + 3) by distributing the negative sign.
