How do i figure out the instantaneous rate of change with given graph and it says find the rate at t = 6 s

Math 
bobpursley,
I would look at rate of change (slope) of the graph.
If the graph is horizonal, rate of change is zero
If the graph is sloping, the slope is the rate of change. 
Math 
Jay,
Do i have to make a tangent line?

Math 
Jay,
Also, do i have to use numbers like 5.99 and 6.01 to find the rate of change @ t = 6s
