@rational

Answer 2

if f'>0 then f is increasing there
if f'<0 then f is decreasing there

Answer 3

so what does f'>0 mean?
well that means the graph of f' is above the x-axis

also f'<0 means the graph of f' is below the x-axis

Answer 4

your question is basically asking you where if f' above the x-axis (you know since it want to know where f is increasing )

Answer 5

where is f' *

Answer 6

@myininaya 0 to 4 so d?
