To solve this problem using the Intermediate Value Theorem, we need to show that there is a root of the equation \( e^x = 4 - 3x \) in the specified interval \( (0, 1) \).

### Step-by-Step Solution:

1. **Reformulate the Equation:**

   The given equation is:
   \[
   e^x = 4 - 3x
   \]

   We define a function \( f(x) \) such that:
   \[
   f(x) = e^x - (4 - 3x) = e^x - 4 + 3x
   \]

   We want to show that there is a root for \( f(x) = 0 \) in the interval \( (0, 1) \).

2. **Check Continuity:**

   The function \( f(x) = e^x - 4 + 3x \) is composed of continuous functions (an exponential function and linear functions), so it is continuous on the interval \( [0, 1] \).

3. **Calculate \( f(0) \) and \( f(1) \):**

   - For \( x = 0 \):
     \[
     f(0) = e^0 - 4 + 3(0) = 1 - 4 = -3
     \]

   - For \( x = 1 \):
     \[
     f(1) = e^1 - 4 + 3(1) = e - 1
     \]

   We know that \( e \approx 2.718 \), so:
   \[
   f(1) \approx 2.718 - 1 = 1.718
   \]

4. **Apply the Intermediate Value Theorem:**

   Since \( f(x) \) is continuous on the interval \( [0, 1] \), and we have:
   \[
   f(0) = -3 < 0 \quad \text{and} \quad f(1) \approx 1.718 > 0,
   \]
   there exists some number \( c \) in the interval \( (0, 1) \) such that:
   \[
   f(c) = 0
   \]

### Conclusion:

By the Intermediate Value Theorem, there is a root of the equation \( e^x = 4 - 3x \) in the interval \( (0, 1) \).

### Filling in the Blanks:

- \( f(0) = -3 \)
- \( f(1) = e - 1 \)
- Since \( f(0) < 0 < f(1) \), there is a number \( c \) in \( (0, 1) \) such that \( f(c) = 0 \).
