You have to plug each one into the appropriate equation for the function. The function you have in your attached file tells you where it is defined.
Now if you plug each one into its appropriate equation you will get the answers.
How do I know which is the appropriate one?
Lets look at it this way. The first line reads 2x+1 if -2
@JosephTheAusom so -1 would work for that one
yes negative one would work for that part. You just plug it in and solve
I got -1 for f(-1) it looks like f(-2) would be undefined then?
would f(1) work in 3x-2?
since its 1 <= x <2
yes because it use <= which means it includes the value. I think you are catching on.
For f(1) I got 1 for f(0) im a little confused where that one goes would it be the 3x^2+2 the reason I ask is because 0
@JosephTheAusom Does this look right? f(-2) = undefined f(-1) = -1 f(0) = 2 f(1) = 1
ok all of those are right except f(0). You had that one correct in the previous post. And reasoning for it was spot on in that post too. It should be f(0)=1
so f(0) =1 and f(1)= 1 too?
so in this problem we don't use 3x^2+2
Oh ok I see it now I use the first formula thanks for you help :)
Yes absolutely, sorry for the late reply!
