Question

Please help see attachments.... thanks

Answer 1

for part a simply look for where the y values pf the graph are getting bigger, so that bould be on (1,4) and (5,6)

part b is a little harder to see because the graph is not very smooth, but you are looking for where the slope of the tangent lines is decreasing. this looks to be on (3,4.5) and (5.5,7)

part c is where the slope of the tangent line = 0 and the graph is concave up, so x=1 and x=5

part d is where the graph changes concavity, which is again difficult to see due to the quaity of the graph, but it looks like x=3, x=4.5, x=5.5, and x=7

Answer 2

kinda still confuse though

Answer 3

on which part?

Answer 4

all part bcos the answers are not quite right
