Answer
(a) red curve.
(b) blue curve.
(c) green curve.
(d) See explanations.
Work Step by Step
(a) Graph $y=(x-2)^2$ as shown in the figure (red curve).
(b) Graph $y=(x+1)^2$ as shown in the figure (blue curve).
(c) Graph $y=(x+3)^2$ as shown in the figure (green curve).
(d) Compared to the graph of $y=x^2$, (a) can be obtained by shifting $y=x^2$ 2 units right, (b) can be obtained by shifting $y=x^2$ 1 unit left, (c) can be obtained by shifting $y=x^2$ 3 units left.
