Compare the graph of the function with the graph of f(x) = IxI. Describe the transformation. g(x) = (1/3)Ix + 6I – 1

Express the function as a piecewise-defined function.
f(x) = 6 IxI

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).
