The graph of f(x) = x6 – 2x4 – 5x2 + 6 is shown below. how many roots of f(x) are rational numbers? 1

B

Step-by-step explanation:

the roots would be 1 and -1 when it comes to the graph

1,-1 are rational numbers

Step-by-step explanation:

Given equation:

Roots of f(x) are :

⇒

⇒

⇒

⇒

from these roots only -1,1 is consider as rational numbers as all integers are rational numbers.

Rest are irrational numbers.
