The x-coordinate of the x-intercept in quadrant || for the given function is -1.
x = -1.
Coordinates are a set of values that helps to show the exact position of a point in the coordinate plane.
We have,
x-intercept in quadrant ||.
f(x) = x³ - x² - x + 1
x-intercept means y = 0 so,
f(x) = y
0 = x³ - x² - x + 1
We see that,
when x = -1 we get,
f(x) = -1 - 1 + 1 + 1 = 0
When x = 1 we get,
f(x) = 1 - 1 - 1 + 1 = 0
But we can not take x = 1 because in quadrant || x is a negative value.
Thus,
The x-coordinate of the x-intercept in quadrant || for the given function is -1.

ANSWER
The x-coordinate of the x-intercept of the function is .
EXPLANATION:
The x-intercept refers to the point where the function meets or cuts the x-axis.
At the x-intercept, .
This means we have to equate the whole function to zero and solve for .
According to the rational roots theorem, the possible rational roots of the equation are .
We now plug in these possible rational roots to see which of them are real roots.
Since , is a root.
By the factor theorem, is a factor of the function.
We now divide the polynomial function, by to find the remaining roots.
See long division in diagram.
This means that .
Or
Hence the roots are or
In the second quadrant the x-coordinate is negative
Therefore, the x-coordinate of the x-intercept of the function is .
