Question
The point \( P(3, 16) \) lies on the curve \( y = x^2 + x + 4 \). If \( Q \) is the point \( (x, x^2 + x + 4) \), find the slope of the secant line \( PQ \) for the following values of \( x \).

- If \( x = 3.1 \), the slope of \( PQ \) is: [ ]
- If \( x = 3.01 \), the slope of \( PQ \) is: [ ]
- If \( x = 2.9 \), the slope of \( PQ \) is: [ ]
- If \( x = 2.99 \), the slope of \( PQ \) is: [ ]

Based on the above results, guess the slope of the tangent line to the curve at \( P(3, 16) \). [ ]
