Answer

The graph of is obtained by shifting the graph of to the left by 4 units and then shrinking it vertically by a factor of .

Solution

  1. Start with the parent function .
  2. The expression indicates a horizontal shift. Since is replaced by , the graph shifts to the left by 4 units (not to the right).
  3. The multiplication by outside the squared term affects the vertical direction. Multiplying by a factor less than 1 causes a vertical shrink (compression), not a stretch.
Thus, the correct description is:
  • Shifting of to the left 4 units and vertical shrinking of the resulting graph by a factor of .

Extra Insights

First, let’s break down the function . The transformation begins with the parent function . The term indicates a horizontal shift to the left by 4 units. Then, the multiplication by signifies a vertical shrinking of the graph by a factor of 3, not stretching.
Next, let’s clarify the common mix-up: many students think shifting and stretching are the same across all dimensions. Remember, shifting directly refers to moves along the axes while stretching or shrinking affects the shape of the graph itself. So, make sure to track those transformations step by step!
