APFIVE Limit of a Rational Function by Factoring
Solve the equation: $$\lim_{t\to5}\frac{t^2-t-20}{t-5}$$.
| t | f(t) |
|---|---|
| 4.9 | 8.9 |
| 4.99 | 8.99 |
| 5.01 | 9.01 |
| 5.1 | 9.1 |
A
$$9$$
B
$$4$$
C
$$5$$
D
Not enough information because the denominator becomes zero at $$t = 5$$, neglecting the cancellation of the removable discontinuity.
