APFIVE Estimating a Limit From a Table
Given the table below which shows values of the function $$f(x)=2*x^2+5$$ for values of $$x$$ near 3, determine $$\lim_{x \to 3} f(x)$$.
| x | f(x) |
|---|---|
| 2.8 | 20.68 |
| 2.9 | 21.82 |
| 3.0 | 23.00 |
| 3.1 | 24.22 |
| 3.2 | 25.48 |
A
$$22$$
B
The limit does not exist because the function is discontinuous at x=3.
C
$$23$$
D
$$23.5$$
