The graph of y=f(x)y = f(x)y=f(x) is shown below.

The coordinates of the maximum point of this curve are (1,4)(1, 4)(1,4).
Write down the coordinates of the turning point of the curve with equation
y=f(x+3)y = f(x + 3)y=f(x+3)
y=−f(x)y = -f(x)y=−f(x)
y=f(x)−3y = f(x) - 3y=f(x)−3
y=f(−x)y = f(-x)y=f(−x)
