1. Problem Description

The problem asks us to draw the graph of g(x)=f(x)4g(x) = f(x) - 4 in the first coordinate grid and g(x)=f(x1)g(x) = f(x - 1) in the second coordinate grid, given the graph of f(x)f(x) in red in both grids.

2. Solution Steps

For the first coordinate grid, we need to graph g(x)=f(x)4g(x) = f(x) - 4. This transformation represents a vertical shift of the graph of f(x)f(x) downwards by 4 units.
Let's identify three key points on the graph of f(x)f(x):
Point 1: (4,0)(-4, 0). Then for g(x)g(x), the corresponding point is (4,04)=(4,4)(-4, 0-4) = (-4, -4).
Point 2: (1,2)(-1, 2). Then for g(x)g(x), the corresponding point is (1,24)=(1,2)(-1, 2-4) = (-1, -2).
Point 3: (4,1)(4, -1). Then for g(x)g(x), the corresponding point is (4,14)=(4,5)(4, -1-4) = (4, -5).
For the second coordinate grid, we need to graph g(x)=f(x1)g(x) = f(x - 1). This transformation represents a horizontal shift of the graph of f(x)f(x) to the right by 1 unit.
Let's identify three key points on the graph of f(x)f(x):
Point 1: (4,0)(-4, 0). Then for g(x)g(x), the corresponding point is (4+1,0)=(3,0)(-4+1, 0) = (-3, 0).
Point 2: (1,2)(-1, 2). Then for g(x)g(x), the corresponding point is (1+1,2)=(0,2)(-1+1, 2) = (0, 2).
Point 3: (4,1)(4, -1). Then for g(x)g(x), the corresponding point is (4+1,1)=(5,1)(4+1, -1) = (5, -1).

3. Final Answer

For the first grid, plot the points (4,4)(-4, -4), (1,2)(-1, -2), and (4,5)(4, -5).
For the second grid, plot the points (3,0)(-3, 0), (0,2)(0, 2), and (5,1)(5, -1).
