help with this question ppl

From the graph they have handily given you, you know that:

$a(x+b)=x[br]$
and:
$[br]a(x+b)=-x[br]$

Can you do the rest?

Alternatively notice that it is just a transformation of $y=|x|$. You should be able to easily find b then, and then a.

Spoil sport stop stalking me.

why is b=0.25 and not 0.5?

I don't get b as either of those... which past paper is this?

Yeah... I didn't get b=1/2 or 1/4, I thought I might have done something wrong but I am pretty confident in what I got.

sorry i meant a :/ but i didnt read the mark scheme properly
why cant it be a(-x-b)=-x
or a(-x-b)=x
for the second part

Look at the graph and the points at which the 2 lines intersect.

I appreciate the help from the previous question and im stuck on question 5. I understand to use the product rule but not the not until i have got the full differential equation and not simplified yet. after that i dont know how to get the result. thanks.

you know when doing proofs you can say even number is 2x, odd number is 2x+1, what others are there e.g. A prime number?
Because i really struggle on these
