Final answer:
Finding real zeros of a function often requires the use of the quadratic formula, where you substitute the coefficients of the quadratic equation (ax² + bx + c = 0) into the formula and solve for x.
Step-by-step explanation:
To find all real zeros of a given function, we can apply the quadratic formula. The function presented in the question is not clear, but based on the provided information, we can discuss how to use the quadratic formula for a general quadratic equation, which is of the form ax² + bx + c = 0.
For example, for a quadratic equation with coefficients a = 1, b = 0.0211, and c = -0.0211, we can substitute these into the quadratic formula:
−b ± √(b² − 4ac)
----------------------------------
2a
This yields:
−0.0211 ± √(0.0211)² − 4(1)(−0.0211)
-------------------------------------------------------
2(1)
This allows us to find the real zeros of the quadratic function.
