How many x intercepts appear on the graph of this polynomial function?
f(x) = x^4 - x^3 + x^2 - x
A) 1 x intercept
B) 2 x intercepts
C) 3 x intercepts
D) 4 x intercepts

Respuesta :

The correct answer is B.


When you factor the polynomial you get the following:


f(x) = (x^2 + 1)(x)(x - 1)


The last two parenthesis give you the intercepts of 0 and 1. The first parenthesis will give you two non-real zeros, but these are not visible in a graph as the question asks.

Answer:B
