To find the zeros of the quadratic function
, we need to solve the equation
.We can use the quadratic formula to solve this equation. The quadratic formula is given by:
where
,
, and
are the coefficients of the quadratic equation
.In this case,
,
, and
. Plugging these values into the quadratic formula, we get:
Simplifying the expression inside the square root, we have:
Therefore, the zeros of the quadratic function
are
and
.Rounding these values to the nearest thousandths, we get:
and
So, the correct answer is
.
