### Objective #7: Graph Functions Involving a Sequence of Transformations

A function involving more than one transformation can be graphed by performing transformations in the following order:

#### Transformations and Their Effects

1. **Horizontal Translations**
   - **Function:** \( y = f(x - h) \)
   - **Effect:** Shifts \( f \) to the right by \( h \) units.
   - **Function:** \( y = f(x + h) \)
   - **Effect:** Shifts \( f \) to the left by \( h \) units.

2. **Horizontal Stretching or Shrinking**
   - **Function:** \( y = f(bx); b > 1 \)
   - **Effect:** Horizontally shrinks \( f \) by dividing each of its \( x \)-coordinates by \( b \).
   - **Function:** \( y = f(bx); 0 < b < 1 \)
   - **Effect:** Horizontally stretches \( f \) by dividing each of its \( x \)-coordinates by \( b \).

3. **Vertical Stretching or Shrinking**
   - **Function:** \( y = af(x); a > 1 \)
   - **Effect:** Vertically stretches \( f \) by multiplying each of its \( y \)-coordinates by \( a \).
   - **Function:** \( y = af(x); 0 < a < 1 \)
   - **Effect:** Vertically shrinks \( f \) by multiplying each of its \( y \)-coordinates by \( a \).

4. **Reflections**
   - **Function:** \( y = -f(x) \)
   - **Effect:** Reflects \( f \) about the x-axis by changing the signs of \( y \).
   - **Function:** \( y = f(-x) \)
   - **Effect:** Reflects \( f \) about the y-axis by changing the signs of \( x \).

5. **Vertical Translations**
   - **Function:** \( y = f(x) + k \)
   - **Effect:** Shifts \( f \) upward by \( k \) units.
   - **Function:** \( y = f(x) - k \)
   - **Effect:** Shifts \( f \) downward by \( k \) units.

**Note:** To calculate the actual horizontal translation when given \( af(bx
