Find the derivative of y= (3x –1) 2with respect to x.
1 answer:
Answer:
dy/dx = 18x – 6
Step-by-step explanation:
y = (3x – 1)²
Take derivative using power rule and chain rule:
dy/dx = 2 (3x – 1) × 3
dy/dx = 6 (3x – 1)
dy/dx = 18x – 6
You can check this answer by simplifying y before taking the derivative.
y = 9x² – 6x + 1
dy/dx = 18x – 6
