Let's solve the problem step by step.

### Part (a)
We need to evaluate the function $$ g(x) = 7 - 2x + x^2 $$ for $$ x = 0, 1, 2, 3, 4 $$.

1. **For $$ g(0) $$**:
   $$
   g(0) = 7 - 2(0) + (0)^2 = 7
   $$

2. **For $$ g(1) $$**:
   $$
   g(1) = 7 - 2(1) + (1)^2 = 7 - 2 + 1 = 6
   $$

3. **For $$ g(2) $$**:
   $$
   g(2) = 7 - 2(2) + (2)^2 = 7 - 4 + 4 = 7
   $$

4. **For $$ g(3) $$**:
   $$
   g(3) = 7 - 2(3) + (3)^2 = 7 - 6 + 9 = 10
   $$

5. **For $$ g(4) $$**:
   $$
   g(4) = 7 - 2(4) + (4)^2 = 7 - 8 + 16 = 15
   $$

Thus, we have:
- $$ g(0) = 7 $$
- $$ g(1) = 6 $$
- $$ g(2) = 7 $$
- $$ g(3) = 10 $$
- $$ g(4) = 15 $$

### Part (b)
Now, let's find the range of $$ g $$. The values we calculated are:
- $$ g(0) = 7 $$
- $$ g(1) = 6 $$
- $$ g(2) = 7 $$
- $$ g(3) = 10 $$
- $$ g(4) = 15 $$

The unique values are $$ 6, 7, 10, 15 $$.

Therefore, the range of $$ g $$ is:
$$
\text{Range of } g = \{6, 7, 10, 15\}
$$
(a) $$ g(0) = 7 $$, $$ g(1) = 6 $$, $$ g(2) = 7 $$, $$ g(3) = 10 $$, $$ g(4) = 15 $$ (b) The range of $$ g $$ is $$ \{6, 7, 10, 15\} $$.
