2e^x  using the shortcut for derivatives is what? Also would 3x = 0 using the shorcut?

The shortcut is where you multiply the first number by the power then subtract one from the power for the answer.

Ex. 2x^3 = 6x^2

You do not find the derivative of 3x=0

You find the derivative of   y=3x

 

 

y=3x1dydx=13x11dydx=3x0dydx=3

 

Also remember that the derivative of the function is the gradient of the tangent at any given point.

y=3x is a line.  the gradient is ALWAYS 3

 

The derivative of e^x is e^x   so the derivative of  3e^x   IS    3e^x
