Piecewise Functions

[abbeyk791]

I understand the concept of piecewise functions I just need help as to what this means because I’m so so confused and it’s stressing me out, it is relating to greater than and less than sort of stuff

 

[Dr.Peterson]

That may just be a typo for \(x\ge2\); if you would show the whole thing, I could say more. You zoomed in a little too far -- context very important in defining symbols.

 

[abbeyk791]

It can be viewed in questions 17,19 and 23. The fact that it’s been used three times is making me think it isn’t a typo

 

[Dr.Peterson]

Very odd. It always occurs where I'd expect \(\ge\) -- except in #15, which you didn't mention.

Are there solutions given for any of these, so you could confirm that it has the meaning I expect, namely "any case other than those whose meaning is clear"? I still think it has to be a mistake, unless you can find a definition of the symbol in the book.

I was unable to find a definition but in question 15, both f(1) and f(-1) used the bottom equation, and in question 19 neither f(-1) or f(3) used the equation with the symbol, my best bet was it meant either + or - but I could be wrong

Still very odd. In #15, f(1) definitely does not use the bottom expression, and in #19, f(3) can't use the bottom expression. Are you saying that a solution was given that did this? Please show it!
