1) The first graph is the graph of f(x) traslated 5 units to the left, then the equation of this graph is: y=(x+5)^2
2) The second graph is the graph of f(x) traslated 5 units upward, then the equation of this graph is: y=x^2+5
3) The third graph is the graph of f(x) traslated 5 units downward, then the equation of this graph is: y=x^2-5
4) The fourth graph is the graph of f(x) traslated 5 units to the right, then the equation of this graph is: y=(x-5)^2
