Answer

$(a)$ See the Blue graphs on the image above. $(b)$ See the Red graphs on the image above. $(c)$ Value of $c$ shifts the graph of $x^2$ either left-hand side or right-hand side by $c$ units.

Work Step by Step

The base of the function $x^2$ has a form of the Black graph on the image above. $(a)$ See the Blue graphs on the image above. By subtraction, the graph moves to the right-hand side by $c$ units. $(b)$ See the Red graphs on the image above. By addition, the graph moves to the left-hand side by $c$ units. $(c)$ Value of $c$ shifts the graph of $x^2$ either left-hand side or right-hand side by $c$ units.
