Below is a graph of f(x)=2x What do you think the graph of f’(x) would look like?
What is this???? The Derivatives of Exponential Functions Calculate the derivative of f(x)=2x
The Derivatives of Exponential Functions Fill out the following table for values of h close to zero.
The Derivatives of Exponential Functions Fill out the following table for values of h close to zero. This table suggests that the limit DOES exist, and has a value of about 0.693 So we can write:
So the derivative of 2x is proportional to 2xwith a constant of proportionality 0.693. Hmmmm…
The Derivatives of Exponential Functions Calculate the derivative of f(x)=ax What is this????
Use your calculator to plot these points. What type of function does it look like? Here is for different values of a
