Answer:
hmm
Step-by-step explanation:
The coefficients of x4 is 9. It has factors of 1, 3, and 9. The constant is 4. It has factors of 1, 2, and 4.
The (positive and negative) ratios of the factors of the coefficient of the x4 and the constant 4 are the potential rational roots of the function.
The answers are:
1, -1, 3, -3, 9, -9, 1/2, -1/2, 3/2, -3/2, 3/4, -3/4, 9/2, -9/2, 9/4, -9/4
Potential roots have the format
factors of the constant term

factors of the initial term
Here, 7/3 is the only possible root that has a 7 in the numerator and a factor of 9 in the denominator.
Verify that 7/3 is a root using synthetic division.
Minus 1 on both sides
Divide by 3 on both sides
C 5 > 7/3
He should choose the second option because he will be paid more money, with the percentage he expects.
Hope this helps!
