1. ## 5 review questions, Function,log etc

Just looking to see if someone could check my answers. They were real easy. I didnt know how to do number 3 so if someone could help me. I am really bad with my graphing calc. Like I said they all seemed easy so I probably got them wrong lol. Thanks for the help last week, I aced my exam. THanks in advance.

1 thru 4 are incorrect

3. great lol, I will revise them

4. Ok I think I fixed them. I think I did some steps different and I forgot that about neg exponents. Also it was #3 that I was lost on.

5. fixed ones look fine.

for #3 ...

$\displaystyle y = e^{x-5} + 2$

the parent function is $\displaystyle y = e^x$

you have two transformations ... the exponent $\displaystyle (x-5)$ causes a horizontal shift of $\displaystyle y = e^x$ 5 units to the right, the final $\displaystyle +2$ is a vertical shift of $\displaystyle y = e^{x-5}$ up two units.

6. I am tracking now. Thanks for explaining. Number three would then look like D. Does number 5 look right? I know that you said 1-4 were originally wrong. I gave you another forum thanks
