To find the zeros of the function $$ f(x) = 2.17x^2 - 3.88 $$, we set $$ f(x) = 0 $$ and solve for $$ x $$:

$$
2.17x^2 - 3.88 = 0
$$

$$
2.17x^2 = 3.88
$$

$$
x^2 = \frac{3.88}{2.17} \approx 1.788
$$

$$
x = \pm \sqrt{1.788} \approx \pm 1.337
$$

Thus, the zeros of the function, to three decimal places, are:

**zero(s) = -1.337, 1.337**
zero(s) = -1.337, 1.337
