A⇢ It's still hence , it's flat
B⇢ It's climbing up ,hence , it's increasing
C⇢ It's still ,hence, it's flat
D⇢ It's descending down ,hence , decreasing
E⇢It's descending down ,hence , decreasing
F⇢It's descending down ,hence , decreasing and it's negative too
G⇢ It's still ,hence it's flat & negative cause it's in 4th quadrant
H⇢Now , it's climbing up , making the graph increase
