The value for x that is a double root of this function is x = -1
<h3>How to determine the double root?</h3>The function is given as:
f(x) = x^3 - 3x - 2
From the graph of the above function (see attachment), we have the following highlights:
- The curve crosses the x-axis at x = 2
- The curve touches the x-axis at x = -1
The point that it touches the x-axis is the double root point
Hence, the value for x that is a double root of this function is x = -1

Answer:
D) 91
Step-by-step explanation:
For the normal approximation, we need that:
np > 5 and np(1-p) > 5
In this question:
So
A) 10
n = 10, then
10*0.89 = 8.9 > 5
10*0.89*0.11 = 0.979 < 5
Does not satisfy.
B) 11
n = 11, then
11*0.89 = 9.79
11*0.89*0.11 = 1.0769 < 5
Does not satisfy
C) 30
n = 30
30*0.89 = 26.7
30*0.89*0.11 = 2.937 < 5
D) 91
n = 91
90*0.89 = 80.1
90*0.89*0.11 = 8.881 > 5
So this satisfies, and 91 is the answer
