  1. I still don't understand what even and odd functions are. I know that f(-x)=f(x) for an even function and f(-x)=-f(x) for an odd function, but I don't understand why that is important to know and some of the problems have been difficult so far.

  2. What do the graphs of functions with fractions like 1/X look and how are they changed when they are transformed?

  3. How would one go about finding the difference quotient of a division problem? Example: Find the difference quotient of 12/x. Would it be the same process as all other difference quotients or is there a special property when you have a difference in a difference quotient?

  4. Are even functions simply functions that are symmetrical about their y-axis, or is it more complicated than that? How so?

  5. I am still unsure about the specifics in reflecting a function over the x and y axis's.

  6. How do you find the difference of two functions in order to graph them?

  7. I still don't understand how to evaluate difference quotients.Do you always use the same equation or does it depend of the f(x) value you have?

  8. I'm still confused as to why transformations along the x-axis are opposites. for example, f(x)=(x-2) moves the eqaution right and not left, but why is this?

  9. How do you find the domain of a square root function?

  10. When you are transforming functions and it were to be f(x)= (x-3)+ 4 does it matter if you shift the graph up 4 or to the right 3 first? And if so why?

  11. How do you find the domain of a composite function?

  12. I still can't understand the relation between even or odd functions and the existence of their inverse function

  13. In problems 51-56 in section 1.4, I am confused on how to determine adding, subtracting, multiplying, dividing the values f(x) and g(x) when given a graph of points.

  14. Even and odd functions still don't make much sense to me. I was able to figure out to use them and solve problems but the idea still really confuses me.

  15. Im confused about the graphing combination functions. Is there a certain effect that adding/subtracting/multiplying/dividing fuctions has on their graphs?

  16. I have trouble about graphing combination functions. When given two equations or when shown two different graphs and told to combine them by an operation (adding/subtracting/multiplying/dividing), I'm not sure how to do that.
