Given a word problem, I can write an absolute value equation or inequality, graph the function and use each to answer
additional questions.
I can graph an absolute value equation or inequality both by hand and using a calculator.
Given a graph, I can write the equation of an absolute value equation or inequality.
I can identify the vertex of an absolute value equation, including those represented in graphical form and as an equation.
1. Identify the parts of the equation.
Graph the function.

3. A company’s guidelines call for
each can of soup produced not to vary
from its stated volume of 14.5 fluid
ounces by more than 0.08 ounces.
Write and solve an absolute value
inequality to describe acceptable can
volumes.
4. A school system is buying new computers. They will buy desktop computers costing $1000
per unit, and notebook computers costing $1200 per unit. The total cost of the computers
cannot exceed $80,000.
a. Write an inequality that describes this situation.
b. Graph the inequality.
c. If the school wants to buy 50 of the desktop computers and 25 of the notebook
computers, will they have enough money?
