Answer

The possible rational zeros of the function f(x)=7x33x2x+2 are ±1,±2,±17,±27

Steps

Step 1 :Given the function f(x)=7x33x2x+2.

Step 2 :We use the Rational Root Theorem which states that if a polynomial has a rational root, then it must be a factor of the constant term divided by a factor of the leading coefficient.

Step 3 :In this case, the constant term is 2 and the leading coefficient is 7.

Step 4 :The factors of 2 are 1 and 2, and the factors of 7 are 1 and 7.

Step 5 :Therefore, the possible rational roots are ±1,±2,±17,±27.

Step 6 :The possible rational zeros of the function f(x)=7x33x2x+2 are ±1,±2,±17,±27
