Question 02 (d) 

Sketch a single function satisfying all of the listed criteria.

Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? 
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! 
Hint 

What function is the same as its derivative? This question is asking you to draw an example of this type of function. 
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.

Please rate my easiness! It's quick and helps everyone guide their studies. Any exponential function of the form , where is a real number, will satisfy the equation above because for k = ln(a). One example would be our favorite . Here k = ln(e) = 1 and a graph is shown below.
