Question 1
Calculate the derivative of y = f(x) = 3 x(4x + 7)
Your answer:

​

Answer 1

`(dy)/(dx) = 24 x + 21`

Explanation:

Explanation:-

Given that the function

y = f(x) = 3 x ( 4 x + 7)

y = 3 x ( 4 x + 7)

y = 12 x² + 21 x ..(i)

Differentiating equation (i) with respective to 'x' , we get

`(dy)/(dx) = 12 (2x) +21 (1)`

`(dy)/(dx) = 24 x + 21`
