According to the Rational Root Theorem, which number is a potential root of f(x) = 9x8 + 9x6 – 12x + 7?

.

Step-by-step explanation:

According to the Rational Root Theorem, the potential roots of a polynomial are

where, p is a factor of constant and q is a factor of leading term.

The given polynomial is

Here, 9 is the leading term and 7 is constant.

Factors of 9 are ±1, ±3, ±9.

Factors of 7 are ±1, ±7.

Using rational root theorem, the rational or potential roots are

Therefore, the potential root of f(x) are .  

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
