yes thank you very helpful and well explained, but what about a? and negative a?

[@chriswilliams5291]

Hi Mario. Thanks for the excellent explanations in your videos. I am having trouble with graphing log[(x - 4)(x + 1)] I can see the vertical asymptotes are x= -1 and x = 4. I was also able to graph it using a calculator, but I was wondering can this sort of problem be graphed using the rules of transformations or does this sort of problem require a calculator to complete?

[@shauryakalra5268]

Great video! How would you graph an equation that is 2log (x-1) + 4? Base is 3. Thanks!
