Graph y = x3 + 4x2 – 7x – 10.
Hint
P(2) = (2)3 + 4(2)2 – 7(2) – 10 = 0
Answer
Graph f(x) = -x3 – 2x2 + x + 2.
f(1) = -(1)3 – 2(1)2 + (1) + 2 = 0
Graph y = x4 – 5x2 + 4.
P(1) = (1)4 – 5(1)2 + 4 = 0
Graph y = -x5.
P(0) = -(0)5
Graph y = 2x3 + x2 – 2x – 1.
P(1) = 2(1)3 + (1)2 – (2) – 1 = 0
Graph y = x4 – 13x2 + 36.
P(2) = (2)4 – 13(2)2 + 36 = 0
Graph f(x) = x4 – 10x2 + 9.
f(1) = (1)4 – 10(1)2 + 9 = 0
