Let's work through each question step by step.

### Question 1
The given exponential function is \( y = 0.5(6^x) \).

1. **Y-Intercept**:
To find the y-intercept, set \( x = 0 \):
\[
y = 0.5(6^0) = 0.5(1) = 0.5.
\]
Thus, the y-intercept is \( (0, 0.5) \).

**Response**: The y-intercept is \( 0.5 \).

### Question 2
The given exponential function is \( y = 5(14^x) \). We need to calculate the y-values for the x-values of \( -2, -1, 0, \) and \( 1 \).

1. For \( x = -2 \):
\[
y = 5(14^{-2}) = 5\left(\frac{1}{14^2}\right) = 5\left(\frac{1}{196}\right) = \frac{5}{196} \approx 0.0255.
\]

2. For \( x = -1 \):
\[
y = 5(14^{-1}) = 5\left(\frac{1}{14}\right) = \frac{5}{14} \approx 0.3571.
\]

3. For \( x = 0 \):
\[
y = 5(14^0) = 5(1) = 5.
\]

4. For \( x = 1 \):
\[
y = 5(14^1) = 5(14) = 70.
\]

Now we can compile the ordered pairs:

- \((-2, 0.0255)\)
- \((-1, 0.3571)\)
- \((0, 5)\)
- \((1, 70)\)

From the responses you provided, the closest approximation for ordered pairs would likely be:
\((−2, 0.45), (−1, 0.67), (0, 5), (1, 1.50)\) seems wrong based on the calculations above.

None of the sets provided seem to match the values. The correct values are:

- \((-2, 0.0255)\),
- \((-1, 0.3571)\),
- \((0, 5)\),
- \((1, 70)\).

Unfortunately, none of the options correctly reflect the calculated y-values for \( y = 5(14^x) \).

To answer, we conclude:
- **The y-values for x = -2, -1, 0, and 1 are approximately \( (−2, 0.0255) \), \( (−1, 0.3571) \), \( (0, 5) \), \( (1, 70) \)**.
