If the original function f(x) = x² + 1 is shifted to the right 4 units to make the function g(x), which expression would represent g(x)?

• g(x) = x² + 5

• g(x) = x² - 3

• g(x) = (x + 4)² + 1

• g(x) = (x - 4)² + 1

Josh graphed the function f(x) = -2(x - 3)² + 4. He then graphed the function g(x) = -2(x - 3)² - 1 on the same coordinate plane. The vertex of g(x) is

• 5 units below the vertex of f(x)

• 5 units above the vertex of f(x)

• 5 units to the right of the vertex of f(x)

• 5 units to the left of the vertex of f(x)
