Emma wants to model the sides of a pyramid by using a function that includes an absolute value expression. Emma will place the pyramid on a coordinate grid as shown. What function should she use?

A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).

One part of a dog agility course is an obstacle called an A-frame. Assume that the left corner of the A-frame corresponds to the point (0, 0). What function that includes an absolute value expression could you use to model the obstacle?

A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).

The graph of f(x) is shown. What is the range for the domain x < −2 ?

What function g describes the graph of f after the given transformation?
f(x) = IxI; vertically stretched by a factor of 3 and reflected across the x-axis.

Know what the terms vertically stretching and reflection means.

What function g describes the graph of f after the given transformation?
f(x) = IxI; reflected across the x-axis and translated 4 units up.

Read the problem carefully in order to understand the direction of the axes.

Write a function for the graph.
