Let \( f(x)=x^2 \). Given the graph of the function \( f \) and the graph of a function \( g \) which was obtained by shifting the graph of \( f \) (see the picture), choose the function \( g \).
\( g(x) = (x+2)^2-4 \)
\( g(x) = (x-2)^2-4 \)
\( g(x)=(x-4)^2-2 \)
\( g(x) = (x-2)^2+4 \)

In the picture A, we are given the graph of the quadratic function \( f(x)=x^2 \). Use the graph of \( f \) as help to identify which of the graphs given in the picture B is the graph of \( g(x)=\frac32(x+3)^2-2 \). Choose what is the colour of the graph of \( g \). (Note: The graphs in the picture B were obtained by shifting and stretching the graph of \( f \).)

Let \( f(x)=x^2 \). Given the graph of the function \( f \) and the graph of a function \( g \) which was obtained as a vertical shift of the graph of \( f \) (see the picture), choose the function \( g \).
\( g(x) = x^2-3 \)
\( g(x) = (x+3)^2 \)
\( g(x) = x^2+3 \)
\( g(x) = (x-3)^2 \)

In the picture A, we are given the graph of the quadratic function \( f(x)=-2x^2 \). Use the graph of \( f \) as help to identify which of the graphs given in the picture B is the graph of \( g(x)=-2(x+4)^2 \). Choose what is the colour of the graph of \( g \). (Note: The graphs in the picture B were obtained by shifting the graph of \( f \).)

Level: 
B
Let \( f(x)=2x^2 \). Given the graph of the function \( f \) and the graph of a function \( g \) which was obtained as a right shift of the graph of \( f \) (see the picture), choose the function \( g \).
\( g(x) = 2(x-3)^2 \)
\( g(x) = 2(x+3)^2 \)
\( g(x) = 2x^2+3 \)
\( g(x) = 2x^2-3 \)

In the picture A, we are given the graph of the quadratic function \( f(x)=\frac12x^2 \). Use the graph of \( f \) as help to identify which of the graphs given in the picture B is the graph of \( g(x) =\frac12 x^2-2 \). Choose what is the colour of the graph of \( g \).
