Question 9 • Mathematics III

How many x -intercepts appear on the graph of this polynomial function? f of x is equal to x to the 4th power minus x cubed plus x squared minus x

Answer
A
2 x -intercepts
B
3 x -intercepts
C
1 x -intercept
D
4 x -intercepts

Explanation

Factor the polynomial by grouping: x⁴ − x³ + x² − x = x(x − 1)(x² + 1). The real zeros are x = 0 and x = 1; x² + 1 has no real zeros. Therefore, the graph has 2 x-intercepts, matching “2 x-intercepts.”
