X=-3/2. The value of f(-1). All you do is plug the numbers In.
To find the median, add up the frequency column to find how many trains there were in total. There were 44 trains in total in this grouped frequency table, so work out 44 + 1 2 = 45 2 = 22.5. The median is therefore between the 22nd and 23rd values.
Answer:
You are correct. The answer is 
Step-by-step explanation:
First, we need to plug in our x value to the derviative's equation to find the slope of the line tangent to the graph, f

Now that we have found the slope and have a given point: (-1,6) we can use the point slope formula to find the equation of the line tangent to the graph f.
