F(x)=3x^(4)-5x^(3)-5x^(2)+5x+2 the number 3 is an upper bound for the set of roots of this polynomial function true or false

TRUE

Step-by-step explanation: The number 3 is an upper bound because use 3 as a multiplyer of each bcoefficient of the polynomial and at each multiple,subtract the next coefficient from it. if all result after subtraction show positive, then the number used is an upper bound. This method is known as the synthetic division.
