Use the rational zeros theorem to list all possible zeros of the function
Step 1 :Given the function
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
Step 6 :
