(C) Let the polynomial be $p(x) = 3x^{3} - 4x^{2} + 7x - 5$.To find the value at $x = -3$,we substitute $-3$ for $x$ in the polynomial:$p(-3) = 3(-3)^{3} - 4(-3)^{2} + 7(-3) - 5$Calculate the powers:$p(-3) = 3(-27) - 4(9) - 21 - 5$Perform the multiplications:$p(-3) = -81 - 36 - 21 - 5$Sum the negative values:$p(-3) = -143$.
