Estimating a Limit From a Table

Question

The table below shows values of the function $$f(x) = 2x^2 + 5$$ for selected values of $$x$$ near 3. What is the value of $$\lim_{x 	o 3} f(x)$$?

| x   | f(x)         |
|-----|--------------|
| 2.8 | 20.68        |
| 2.9 | 21.82        |
| 3.0 | 23.00        |
| 3.1 | 24.22        |
| 3.2 | 25.48        |

Accepted Answer

$$23$$

Answer

$$22$$

Answer

The limit does not exist because the function is discontinuous at x=3.

Answer

$$23.5$$
