  3. If P(x) = x ^ 4 - 4x ^ 2 + 3x + 2 then P(2)? A.2 B.8 C. 14 D. 20

  4. What is B(x) + S(x) given that B(x) = 7x ^ 2 - 5x + 100 and S(x) = 20x ^ 2 + 60x + 200?

B. 27x ^ 2 - 65x + 200 D. 17x ^ 2 - 45x + 300 A.27x ^ 2 + 55x + 300 C. 17x ^ 2 + 45x + 300

  1. Write a polynomial to express the total value, T(x), of (x + 4) 20-peso bills, (x-3) 50-peso bills, (x + 5) 100-peso bills, and (x-2) bills.

A. T(x)= 20(x+4)+50(x-3)+100(x+5) +200(x-2) B. T(x) = 20(x + 4) - 50(x - 3) - 100(x + 5) - 200(x - 2) C. T(x)= 20(x+4)x50(x-3) x 100(x + 5) x 200(x-2) D. T(x) = 20(x + 4) + 50(x - 3) + 100(x + 5) + 200(x - 2)

P(x) = 7x^3 + 6x^4 - 8x^6 + 6x + 11
f(x) = x^2 - 3x + 2x^4 + 1
P(x) = x^4 - 4x^2 + 3x + 2
B(x) + S(x) = (7x^2 - 5x + 100) + (20x^2 + 60x + 200)
T(x) = 20(x + 4) + 50(x - 3) + 100(x + 5) + 200(x - 2)
