The value for x that is a double root of this function is x = -1
How to determine the double root?
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
