Write the equation of a function that has the given characteristics.
The graph of y = x2, shifted 4 units downward.
O y = x2 + 4
O y = 4x2
O y = x2-4
O x2/4
If you graph both y = x^2 and y = x^2 - 4, you'll be able to see that the equation of function, y = x^2 - 4, is 4 units down from the equation of function y = x^2.
