Find the rate of change

• 1
• 2
• 11
• Not a constant slope/Non-Linear

What is the initial value in this equation?
y=8x+6

• 8
• 6

Compare the initial values of each function.

• The initial value of item I is greater than the initial value of item II.

• The initial value of item I is equal to the initial value of item II.

• The initial value of item II is greater than the initial value of item I.

Compare the initial values of the functions.

• Both functions have the same initial value.

• The initial value of item I is greater than the initial value of item II.

• The initial value of item II is greater than the initial value of item I.

Which linear function has the greatest slope?

• A

• B

• C

• D

Jack is renting a scooter to ride in the city. The rental charges include a fixed charge of $4 and an additional cost of $1.25 per hour. Which equation represents the total rental charge, T, if Jack rents the scooter for n hours?

• T = 4n + 1.25

• T = 1.25n - 4

• T = 1.25n +4

• T= 4n - 1.25

List the types of intervals that the graph demonstrates in order.

• decreasing, constant, increasing, constant
• increasing, decreasing, constant
• increasing, constant, increasing, constant
• increasing, constant, decreasing, constant

Which graph matches the given story:

The population size grows at a constant rate for some time, then doesn’t change for a while, and then grows at a constant rate once again.

• 
• 
• 
• 

How would you describe the graph of the function in interval 2? Select all that apply.

• The function is increasing.

• The slope is negative.

• The function is decreasing.

• The function is constant.

• The slope is positive.

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.
