  1. x

  2. x^2

  3. 1/x

  4. x^3

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When 0 < x < 1, we have x > x^2 > x^3 (since multiplying by x less than 1 decreases value), but 1/x > 1 (since denominator < numerator). Therefore 1/x is the largest among x, x^2, x^3, and 1/x.

AI explanation

To answer this question, we need to evaluate each option and determine which one is the largest when the value of x lies between 0 and 1.

Option A) x - This option is incorrect because when x lies between 0 and 1, it is smaller than x^2, x^3, and 1/x.

Option B) x^2 - This option is incorrect because when x lies between 0 and 1, x^2 is smaller than x^3 and 1/x.

Option C) 1/x - This option is correct because when x lies between 0 and 1, 1/x is larger than x, x^2, and x^3. As x gets closer to 0, 1/x becomes larger.

Option D) x^3 - This option is incorrect because when x lies between 0 and 1, x^3 is smaller than 1/x.

Therefore, the correct answer is C) 1/x. This option is the largest when the value of x lies between 0 and 1.
