Question 15
Algebraic ExpressionsIf f(x − 4) = x2 + 2x + 3, find f(2)
- A.6
- B.11
- C.27
- D.51
Show the answer and explanation
Answer: D (51)
Explanation
f(2) means x − 4 = 2, so x = 6. Then 62 + 2(6) + 3 = 51.
If f(x − 4) = x2 + 2x + 3, find f(2)
Answer: D (51)
f(2) means x − 4 = 2, so x = 6. Then 62 + 2(6) + 3 = 51.
