~Okay, for the first section on the 4th page, you basically have to use your exponent rules, which you can find on the internet or from your Algebra 2 notes. Do you need help with that entire section?
~No idea how to do piecewise functions, sorry. crying
~Oh yeah, for the first problem of the (f o g) thing with the f(x)=2x-1 and g(x)=(x+2)^2-3, you have to compose the equations into each other so the g(x) equation is inside the f(x) equation, like: f(g(x))= 2((x+2)^2-3)-1. Then it becomes f(g(x))= 2(x^2+4x+4-3)-1 because you simplified the (x+2)^2. Next, it becomes f(g(x))= 2(x^2+4x+1)-1. Then it becomes f(g(x))= 2x^2+8x+1 as the final answer. I don't know how to the second problem sad
For my math, have to check my answers to some and I need to do the piecewise mfunctions and the f+g,f-g stff and I need to check all my completeing the square shiz and I have to do a little more, lol. I can help you if you want! ^_^
