Functions Review
RULES 1. Decide which team goes first. 2. Appoint a scorekeeper. 3. Teams answer correctly and earn money. If a team is correct, they can continue until max. 3 times or until they get BAAM! 4. If a team hits BAAM! they go bankrupt! 5. The team with the most money at the end is the winner.
Is the table a linear or non linear function? Linear xy
Say ‘goodbye’ to your money!
yes Is the mapping showing a function?
You are broke!
no Is the table showing a function? xy
Is the table showing a function? yes xy
Where’s your money gone?
Unlucky!
Is the table showing a linear or nonlinear function? nonlinear xy
Oh dear!
nonlinear Is the graph a linear or nonlinear relationship?
Write the equation for a line with a y-intercept of 3 that also passes through the point (2,5). y= x +3
y = 3x + 2 y = 3x – 2 Look at the 2 equations above. Choose the statement that best fits the comparison of the two equations. a) The items have different y-intercepts and different rates of change. b) The rates of change are the same, but the y-intercepts are different. c) The items have the same y-intercepts and the same rate of change. d) The y-intercepts are the same, but the rates of change are different. b
Oops!
Vertical line test What is the name of the method used to look at a graph and decide whether it is a function?
Write the equation for the table. y = -3x – 9 x y
Is the graph showing a linear or nonlinear relationship? linear
Laying on its side Draw a parabola to show when it would NOT represent a function?
yes Is the mapping showing a function?
no Is the graph showing a function?
d Look at the equations above. Choose the statement that best fits the comparison of the two equations. a) The items have different y-intercepts and different rates of change. b) The rates of change are the same, but the y-intercepts are different. c) The items have the same y-intercepts and the same rate of change. d) The y-intercepts are the same, but the rates of change are different.
NO Is the relationship in the mapping showing a function?
y = -2x – 8 Write the equation for the table. x y
You lost everything!
y = 2x +9 Write the equation for the table. xy
