f(x) = (-20 + 6x + 9/2 + 5x + 3)/5
What is f(f(7))* 5 + 6/10?
Looks hard? This question will give you 1000 points if correct but will subtract 500 points if you get it wrong! If you do not want to try pass it on and only lose 100 points. If nobody tries, the question goes back around. First person to go negative is eliminated!

Mr. Bobbieboo is a car salesman! Every week he writes down how many cars he sold and how much money he has in total. He started on week 0 with $150. Each car is worth $20. Graph the equation and decide whether the function is linear, or quadratic or exponential!
YAY + LINEAR

The points, {(0,-8),(5,3),-(90,2),(9,2)} are a:
function

What is a function? When is a relation not a function?
A function is a relation that passes the vertical line test (this means that one x value does not equal two different y values - we are an inclusive society!)

The points, {(3,5),(-1,0),(0,1),(2,2),(3,3)} are a:
relation/not function

Tim's bike's worth decreases overtime. Research shows it decreases by 20% of last year, every year. Draw the graph!
YAY!

f(x) = x/2; g(x) = 2/x
What is g(2) f(6) / f(8)?
3/4
300
What is the vertical line test?
Tests whenever a group of points is a function. Checks that all points don't align with another point when you draw a vertical line.
300
What is the domain of the function: f(x)=2x
x2 points for finding range as well
Domain = R
Range = R

Tommy has planted a flower and a tree. The flower grows at an average rate of 20 inches/year. When he planted his tree, it was already 3 feet. The tree grows 10 inches/year. Which one is the tallest in 3 years?
The tree is bigger as it is 66 inches tall while the plant is 60 inches tall.

Make your own graph with a quadratic function. Explain why the function is quadratic and give a short story about the graph points.
YAY - Quadratic because it creates a parabola!

What is the (quadratic) function that goes through the points (-1, 14), (2, -1), and (5,20)?
(None of these points is the vertex for the function)
You will need to use techniques from ALL the Units. (Hint: Try to find a, b, and c)
f(x) = 2x2 -7x + 5
