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

c. y = x^2 - 4

Step-by-step explanation:

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.

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
