Question 19
IntegrationIntegrate the function 1 − 2x.
- A.x − x2 + k
- B.x + x2 + k
- C.−x − x−2 + k
- D.x − x−2 + k
Show the answer and explanation
Answer: A (x − x2 + k)
Explanation
∫1 dx = x and ∫2x dx = x², so the answer is x − x² + k.
Integrate the function 1 − 2x.
Answer: A (x − x2 + k)
∫1 dx = x and ∫2x dx = x², so the answer is x − x² + k.
