Function d gives the distance of a boat from the dock t seconds after leaving the dock. Distance is measured in meters. Here is a graph that represents d.
select all the statements in function notation that represent the situation.

d(30)=d(70)

d(10)=20

d(90)
d(t)=10 when t is 20

d(0)=0

d(0)=170

d(170)=0
