Find f'(x) for f(x) = -10e**(-2x)

You have to use the Derivative Rules for 'e'.

Explained here very well https://youtu.be/zoaqG9xpV0Q

Thanks for "Math and Science 2024" on YouTube

Find f'(x) for f(x) = -10e**(-2x)

$$f(x)=-10e^{-2x}$$

$$g(x)=e^x\\g'(x)=e^x$$

$$h(x)=-2x\\h'(x)=-2$$

$$f'(x)= -10\times e^{-2x}\times-2\\\color{blue}f'(x)=20e^{-2x}$$
