Question

f(x)=Asin(Bx-C)+D

Coordinates: (-4,-1),(-1,1),(2,-1),(5,-3),(8,-1)

Find the amplitude, period, phase shift, domain, and range.

**Problem Set: Identifying Properties of Trigonometric Functions**

### Instructions:
For problems 8, 9, and 10, identify the amplitude (if appropriate), period, phase shift, domain, and range. Then, write a function in the indicated form for the given graph. If you cannot see the coordinates clearly, zoom in on the graph.

#### Problem 8
Given: \( f(x) = A \sin(Bx - C) + D \)

**Graph Analysis:**
- Coordinates on the graph: 
  - Peak at \((-1, 1)\)
  - Valley at \((5, -3)\)
  - Crosses the x-axis at \((-4, 0)\), \((2, 1)\), and \((8, -1)\)

**Questions:**
- **Amplitude:**
- **Period:**
- **Phase Shift:**
- **Domain:**
- **Range:**

#### Graph Description:
The graph displayed is a sinusoidal curve. Notable points include \((-1, 1)\) as the maximum, and \((5, -3)\) as the minimum. These points help determine the amplitude and vertical shift. The curve crosses the x-axis at \((-4, 0)\), \((2, 1)\), and \((8, -1)\), which helps identify the period and phase shift.

#### Problem 9
Given: \( f(x) = A \tan(Bx - C) + D \)

**Questions:**
- **Amplitude:**
- **Period:**
- **Phase Shift:**
- **Domain:**
- **Range:**
