Final answer:
The equation modeling g(x) after undergoing a right shift of 2 and a downward shift of 3 is g(x) = (x - 2)² + 2. Hence the correct answer is option A
Step-by-step explanation:
To find the equation modeling g(x), which is the graph of f(x) that undergoes a right shift of 2 and a downward shift of 3, we need to apply the corresponding transformations to the original function f(x) = x² + 5. A right shift of 2 means replacing x with (x - 2) and a downward shift of 3 means subtracting 3 from the function. Thus, the equation modeling g(x) is g(x) = (x - 2)² + 2, option a.
