![## Evaluating Functions
### Problem 8:
Given the function \( f(x) = x^2 + x - 8 \), calculate \( f(3) \).
**Solution:**
\[ f(3) = (3)^2 + (3) - 8 \]
\[ f(3) = 9 + 3 - 8 \]
\[ f(3) = 4 \]
### Evaluating Functions from a Table
#### Directions:
Evaluate the function from the table below.
#### Problems:
9. Find \( f(2) \)
10. Find \( f(0) \)
11. Find \( f(-1) \)
#### Table:
| x | \( f(x) \) |
|-----|-------------|
| -1 | -17 |
| 0 | -3 |
| 2 | 0 |
| 3 | 6 |
| 4 | 11 |
Use the table provided to find the function values for \( f(x) \) based on the given \( x \) values.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F21ff12b2-ad5b-4548-b7b5-49d7acea1b65%2Fff32c1d8-f880-433d-9257-3f2748e96a75%2Fvh4owzc_processed.jpeg&w=3840&q=75)
