Decide if the sentence is True or False

a. The graph of the functiongraph of the functiongraph of the function y=2(x‑2)Indeks górny 2 is obtained by shifting the graph of the functiongraph of the functiongraph of the function y=2xIndeks górny 2 by 2 values to the right along the axis X.

b. The graph of the functiongraph of the functiongraph of the function y=-3xIndeks górny 2-2 is obtained as a result of shifting the graph of the functiongraph of the functiongraph of the function y = -3xIndeks górny 2 by 2 values upwards along the axis X.

c. After shifting the functionfunctionfunction graph y=-2xIndeks górny 2 by three values to the left along the X axis, we obtain a graph of the functiongraph of the functiongraph of the function y = -2(x+3)Indeks górny 2.

d. After shifting the graph of the functiongraph of the functiongraph of the function y=xIndeks górny 2 by four values down along the X axis, we get a graph of the functiongraph of the functiongraph of the function y=xIndeks górny 2-4.
