Transforming Polynomial Functions

The graph of y = g(x) shown is the result of shifting the graph of f(x) 3 units to the right and 2 units up. If the equation of g is g(x) = x² - 2x +2, what is the equation of f(x)?

• f(x) = x² + 4x + 3

• f(x) = x² + 4x + 15

• f(x) = x² + 6x + 19

• f(x) = x² - 8x + 15

• f(x) = x² - 8x + 19
