Question 9
DifferentiationThe slope of the tangent to the curve y = 3x2 − 2x + 5 at the point (1, 6) is
- A.4
- B.1
- C.6
- D.5
Show the answer and explanation
Answer: A (4)
Explanation
dy/dx = 6x − 2, which is 6 − 2 = 4 at x = 1.
The slope of the tangent to the curve y = 3x2 − 2x + 5 at the point (1, 6) is
Answer: A (4)
dy/dx = 6x − 2, which is 6 − 2 = 4 at x = 1.
