Question

Find first and second derivative of the following functions:
a.f(x) = 4x + 5x²​

Answer 1

Answer:

First derivative = 4 + 10x

Second derivative = 10

Step-by-step explanation:

Rules :-

$\frac{d {x}^{n} }{dx} = n {x}^{n - 1}$

And, differentiation of constant function is zero.

First derivative of 4x + 5x² = 4 + 10x.

Again differentiating 4 + 10x wrt x , we get

10.
