Understanding Graph Transformations

The video tutorial explains how to graph functions by shifting the graph of f(x) = x. It covers two examples: g(x) = f(x) - 4, which shifts the graph down by 4 units, and h(x) = f(x + 6), which shifts the graph 6 units to the left. The tutorial emphasizes understanding how changes in the function's equation affect the graph's position.

What is the effect of defining g(x) as f(x) - 4 on the graph of f(x)?

• The graph shifts right by 4 units.

• The graph shifts left by 4 units.

• The graph shifts down by 4 units.

• The graph shifts up by 4 units.
