apparently
you see I know how they got the 5
but for the 3 all they did was say
and for some reason that lead them to 3
MAT196F Midterm Test Solutions
it's kind of hard to read but it's the first question
I know they did that
but they said that if
so this give you permission to turn the |2x-1| into a five but to get rid of the
all they said is that it's bigger than one so there
so how does that give them permission to make the that polynomial equal 1
??
I'm sorry, let me try to be a little more clear, it's kind of hard with these kinds of questions though, since I don't understand whats really going on and I just kind of try to work out patterns from the solutions of all the other questions I've solved like these
|2x-1|<5 so that means that I could use 5 instead of this expression
I know they got this from sweet...
and then they go
but where did this come from did they use again somehow??
remember, we stated out with |x - 1|< 1, which is why things played out that way. besides, if x = 0, |2x + 1| is not bigger than 1. we need to make x a range of values here, as we wanted inequalities. the actual value doesn't matter that much. we could have made |x - 1| < 1/2 or whatever. but 1 looks nice
