Module 4 Review Part 2

The graph of f(x) = x is known as the ​ (a)   in a family of linear graphs. 

• first function
• plain function
• parent function

True or false: An arithmetic sequence must have a common multiple.

• True

• False

Determine the next 3 terms in the arithmetic sequence 3, 10, 17, 24, __, __, __.

Write an equation that describes the nth term of the arithmetic sequence

–2, –1.5, –1, –0.5, 0, 0.5, ….

Christa has a box of chocolate candies. The number of chocolates in each row forms an arithmetic sequence, as shown in the table.

 

How many chocolates are there in the 9th row?

• 15

• 24

• 25

• 27

True or false: An absolute value function is an example of a piecewise function.

• True

• False

A(n) ​ (a)   is a type of piecewise function with a graph that is a series of horizontal line segments.

• absolute value function
• linear function
• step function

Describe the transformation of the function in relation to the parent function. Select all that apply.

• Reflected across x-axis

• 
  Vertical stretch

• Reflection across y-axis

• 
  Translated up 3 units

• 
  Translated left 2 units

Match the transformation with the description of its effect on the graph of the absolute value parent function.

• Flipped across axis

• Reflection

• Stretch or compression of the graph

• Translation

• Shifted horizontally or vertically

• Dilation
