# Question: hi i can do most of the prep 2 question...

###### Question details

Hi, I can do most of the Prep 2 question, but not sure how to get an answer when I sub in $\frac{\mathrm{\pi}}{6}$ into the fog equation which I'm pretty sure is $9\mathrm{sin}^2\left(2x\right)+6$. Their answer is 51/4

Also, I was able to do Prep 4 and sketch a possible graph for f[g(x)] but not sure about what equation I'd use for the first graph of Prep 5. I got g(x) = -x^2 + 3 for the 2nd graph.

Thanks as always for your help, Michael
