In a distance versus time graph, a horizontal line represents what?
An object is stationary or not moving.
Identify the independent and dependent variables. Write an equation in function form for the situation.

Independent variable is the number of people.
Dependent variable is the total cost of the amusement park.
f (p) = 6 + 29.99p
Is the following equation a function? Explain.

Yes, the graph will pass the vertical line test.
The table shows the number of points scored by the West Noble football team in the first six games this year. Graph the data and determine whether it is a function or not.
Determine if the sequence is an arithmetic sequence. If so find the next three terms.
-8, -2, 4, 10, . . .
Yes, the next three terms are 16, 22, 28.
In a velocity versus time graph, a horizontal line represent what?
An object is at a constant velocity or their velocity is not changing.
Find the domain and range of the relation below.
{(-2, 0), (-2, 1), (-1, 1), (0, 0), (1, 2), (1, 3)}
D = {-2, -1, 0, 1}
R = {0, 1, 2, 3}
Is the graph a function? Explain.
No, it would fail the vertical line test at almost every point.
What is a discrete graph?
This is a graph of points only. The graph is not connected.

11, 7, 3, -1, . . .
a47 = -173
A squirrel starts walking across the yard at a constant speed, get frightened and speeds up to a run, then slows back down to a walk, get frightened again and speeds up to a run again and finally slows back down to a walk. Which graph represents this situation?
Graph B
A car can travel 30 miles on a gallon of gas and has a 20-gallon tank.
A. Write a function rule.
B. How far can the car travel on 12-gallons of gas?
D(g) = 30g
D(12) = 30(12) = 360 miles
The car can travel 360 miles.
Is the graph a function? Explain.
Yes, It passes the vertical line test.
Use the trend line graphed to predict the number of snowboarding participants in 2008.
There was approximately 66 participants.
Given the first term in a sequence is 17 and the common difference is + 4. Find the 131st term.
a131 = 537
You hike up a mountain path starting at 10am. You camp overnight halfway up the mountain and then at 10 am the next morning you continue hiking up the rest of the mountain. You camp overnight at the top of the mountain and then at 10am the next morning you hike all the way down the mountain. Draw a graph to represent this situation. Notice they are using time and distance measurements!!!

Find the domain and range.
D = -4 <= x <= 4
R = -4 <= y <= 4
Is the equation a function? Explain.
x = 5y2
No, it's graph would not pass the vertical line test.
Roma had guests for dinner at her house eight times and has recorded the number of guests and the total cost for each meal in the table below. Graph the data and use it to predict her cost if she has 9 guest.
Her cost will be approximately $188.
If you have the sequence below, find the the 123rd term.
-158, -145, -132, -119, . . .
a123 = 1428
Write a situation for the given graph.
A marathon runner starts at a steady pace and then runs faster at the end of the race before stopping at the finish line.
The square patch of grass above needs to be seeded around the 4 identical circular ponds. Write a function for the area (A) of grass that needs to be seeded in terms of the radius of the ponds (r).
Area = 16r2 - 4(pi)r2
Is the graph of the cosecant of x a function? Explain.
Yes, it is a function. It would pass the vertical line test.
