Question 12
PolynomialsA polynominal is defined by f(x + 1) = x3 + 3x2 − 4x + 2, find f(2).
- A.−8
- B.−2
- C.2
- D.8
Show the answer and explanation
Answer: C (2)
Explanation
x + 1 = 2 when x = 1, so f(2) = 1 + 3 − 4 + 2 = 2.
A polynominal is defined by f(x + 1) = x3 + 3x2 − 4x + 2, find f(2).
Answer: C (2)
x + 1 = 2 when x = 1, so f(2) = 1 + 3 − 4 + 2 = 2.
