Functions Review

BAAM!

RULES1. 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.

BAAM!

Unlucky!

Is the table showing a linear or nonlinear function?

BAAM!

Oh dear!

Is the graph a linear or nonlinear relationship?

nonlinear

\$10

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 + 2y = 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.

What is the name of the method used to look at a graph and decide whether it is a function?

Vertical line test

Write the equation for the table.

y = -3x – 9
