Pencil is just thought process + me dieing and just writing what I'm thinking.
I wrote 2 methods but I don't recc the second one as it's overly tedious and hence easier to make mistakes. The first method requires you to identify that by transforming the graph by 0.5 units in the positive y-direction u'll get an easier graph to solve. Note that Q wants exact form (albeit annoyingly)
Sorry that I got lazy halfway. Any Qs feel free to ask!

You've forgotten to modulus the integral from x = -2 to x = 0.
-1 + 3e-² is negative
-1 + 3e-² is negative
Ah yea thanks! Made a mistake there
