**Derivative Of 4e X**

### 4. Derived from

Hello,

For this question, note that the derivative of e x is itself e x. Now 4 is just a constant multiplication which is multiplied by e x and can be estimated to get:

Let y = 4. x

dy / dx = 4.e x. (1) = 4e x.

U = X

du / dx = 1.

y = 4. u

dy / du = 4. u

dy / dx = (dy / du) (du / dx) = 4. x.

4. X
