Which ordered pairs lie on the graph of the exponential function f(x)=−32x+5f(x)=−32x+5?

Select **each** correct answer.

To determine which ordered pairs \((x, y)\) lie on the graph of the exponential function \( f(x) = -3 \cdot 2^x + 5 \), we need to evaluate \( f(x) \) for each given value of \( x \) and see if the resulting \( y \)-value matches the second component of the ordered pair.

Let's break it down:

1. **Evaluate the function** \( f(x) = -3 \cdot 2^x + 5 \) for different values of \( x \).
2. **Compare** the result with the given \( y \)-value in the ordered pair.

### Example calculations:
- **For \( x = 0 \):**
  \[
  f(0) = -3 \cdot 2^0 + 5 = -3 \cdot 1 + 5 = -3 + 5 = 2
  \]
  So, the ordered pair \( (0, 2) \) lies on the graph.

- **For \( x = 1 \):**
  \[
  f(1) = -3 \cdot 2^1 + 5 = -3 \cdot 2 + 5 = -6 + 5 = -1
  \]
  So, the ordered pair \( (1, -1) \) lies on the graph.

- **For \( x = 2 \):**
  \[
  f(2) = -3 \cdot 2^2 + 5 = -3 \cdot 4 + 5 = -12 + 5 = -7
  \]
  So, the ordered pair \( (2, -7) \) lies on the graph.

### Summary
- The correct ordered pairs that lie on the graph of \( f(x) = -3 \cdot 2^x + 5 \) are:
  - \( (0, 2) \)
  - \( (1, -1) \)
  - \( (2, -7) \)
