i think you just plug in the terms so w(x) = [2(2x+1)+1]

then if you need to simplyfy and solve for x that's not that hard either, (2(2x+1)+1) (4x+2+1) 4x+3 4x=3 x=3/4

I see where you plug in the 2x+1 for p(x) but how do you decide what the first p in the equation is, confused on that p

p(x) is the function then it is ran through itself again

think of v=p(x) p(v) is the same as the p(p(x)) in the problem given

p, we all had a tough time with functions at one point, later they will seem so natural that it's like addition

it all comes down to putting a number in and getting a number out what your working on now is putting a number in then getting a number out and then putting that number back in to get out the answer
