Algebra 2

1. Warm-up 1
Write the function which takes a
room of 50 m2 and decreases
each dimension by the same
value.

2. Warm-up 2: translate the following into a mathematical
relation
• A presidential candidate in Indonesia must be at least
30 years old, while a presidential candidate in the
United States of America must be at least 35 years
old.

3. Solving Quadratic
Inequalities
What it means to be less than a function

4. FYI: Aligned Common Core State Standards
CCSS: Mathematics, CCSS: HS: Algebra, Creating Equations
HSA-CED.A. Create equations that describe numbers or relationships
HSA-CED.A.1. Create equations and inequalities in one variable and use
them to solve problems. Include equations arising from linear and
quadratic functions, and simple rational and exponential functions.

5. Modeling with quadratic functions
Certain events are accurately modeled by quadratic functions. For
example:
• Area
• Projectiles (objects shot up into the air which are
pulled down by gravity)
• Profit and loss

6. Area
Ms. Ilonka wants her room to be the same
size as Mr. Paul’s room. She wants to increase
the length and the width by the same
amount. Set up an equation and show how
you solve for x. Explain the meaning of x.

7. Area – how many square meters
is Ms. Ilonka’s room post-renovation?
