(B) Let the polynomial be $p(x) = 3x^{3} - 4x^{2} + 7x - 5$.To find the value of the polynomial at $x = 3$,we substitute $3$ for $x$ in the expression:$p(3) = 3(3)^{3} - 4(3)^{2} + 7(3) - 5$Calculate the powers:$p(3) = 3(27) - 4(9) + 21 - 5$Perform the multiplications:$p(3) = 81 - 36 + 21 - 5$Perform the addition and subtraction:$p(3) = 45 + 21 - 5 = 66 - 5 = 61$.Thus,the value of the polynomial at $x = 3$ is $61$.
