To graph the function ƒ(x) = x² - 3, shift the graph of y = x² down ___ units.
The green dotted line in the graph below represents the function f(x). The blue solid line represents the function g(x), which is the function f(x) after it has gone through a shift transformation. Find the equation for g(x).
g(x)=f(x−2)+3
g(x)=f(x−2)−3
g(x)=f(x+2)−3
g(x)=f(x)−3
