Question

please solve it as fast as u can ? no spans ​

Answer 1

Answer:

Let y = 2x………..(1)

Let ∆x be a small change in x.

Let ∆y be the corresponding change in y.

Then y + ∆ y = 2 (x+ ∆ x) = 2x + 2∆x …….(2)

(2)-(1) gives ∆y = 2 ∆x

Divide by ∆ x both sides. We have

∆y/∆x = 2

Lt as ∆ x =>0 (∆y/∆x) = 2

i.e., dy/dx = 2

Hence derivative of 2x is 2
