Question

UpStudy AI · Accepted Answer

To evaluate the function $$ k(x) = \sqrt{x + 2} $$ at $$ x = 8 $$:

$$
k(8) = \sqrt{8 + 2} = \sqrt{10}
$$

Since $$\sqrt{10}$$ cannot be simplified further, the exact answer is:

$$
k(8) = \sqrt{10}
$$

**Answer:**
$$
k(8) = \sqrt{10}
$$
$$ k(8) = \sqrt{10} $$
