Write the set `A={x:x is an integer ,-1 le xlt 4}` in roaster form .

Answer

To write the set \( A = \{ x : x \text{ is an integer}, -1 \leq x < 4 \} \) in roaster form, we will follow these steps:

### Step 1: Identify the range of integers
The set specifies that \( x \) is an integer and that \( x \) must satisfy the condition \( -1 \leq x < 4 \). This means we need to find all integer values starting from -1 up to, but not including, 4.

### Step 2: List the integers within the range
Starting from -1, we will list all integers up to 3 (since 4 is not included):
- The integers are: -1, 0, 1, 2, 3.

### Step 3: Write the set in roaster form
In roaster form, we write the set by listing all the elements within curly braces:
\[ A = \{-1, 0, 1, 2, 3\} \]

### Final Answer
Thus, the set \( A \) in roaster form is:
\[ A = \{-1, 0, 1, 2, 3\} \]
