Answer 3

alright, give me a few minutes to work it out

Answer 4

Answer 5

@jim_thompson5910 you must want to kill me by now but do you wanna help me out yet again?

Answer 6

(f o g)(-5)

is the same as

f( g(-5) )

so if g(-5) = 0, then

f( g(-5) )

is the same as

f( 0 )

Answer 7

So

(f o g)(-5)

is the same as

f( 0 )

Answer 8

so final answer is -2

Answer 9

yes

Answer 10
