Sketch on the same set of axes the graphs of \( f(x)=-2 x^{2}-4 x+6 \) and \( g(x)=-2 \cdot 2^{x-1}+1 \). Clearly indicate all intercepts with the axes, turning point(s) and asymptote(s).

Quick Answer
To sketch the graphs of \( f(x) = -2x^2 - 4x + 6 \) and \( g(x) = -2 \cdot 2^{x-1} + 1 \) on the same axes:
1. **For \( f(x) \)**:
- **Intercepts**:
- x-intercepts at \( x = -3 \) and \( x = 1 \)
- y-intercept at \( (0, 6) \)
- **Turning Point**:
- Vertex at \( x = -1 \), calculate \( f(-1) \) for the y-coordinate.
2. **For \( g(x) \)**:
- **Intercepts**:
- x-intercept at \( x = 1 \)
- y-intercept at \( (0, 0) \)
- **Asymptote**:
- Horizontal asymptote at \( y = 1 \)
3. **Graphing**:
- Plot the intercepts and turning point for \( f(x) \).
- Plot the intercept and asymptote for \( g(x) \).
- Draw the parabola for \( f(x) \) and the exponential decay for \( g(x) \).
This will provide a clear visual of both functions on the same set of axes.
