Answer:

Therefore the zeros of this function are between 1 and 2. So the correct answer is "a".

Explanation:

In order to find the zeros of a function we need to find at which values for "x" make f(x) equal to zero. Therefore we have:


f(x) = x^3 - 2 \\0 = x^3 - 2\\x^3 - 2 = 0\\x^3 = 2\\x = \sqrt[3]{2} = 1.2599

Therefore the zeros of this function are between 1 and 2. So the correct answer is "a".
