Lesson 325 of 1524
9.11 Using Quadratic Expressions in Vertex Form to Solve Problems
F ( 1 ) can be expressed in words as "the value of f when x is 1." Find or compute
Practice this chapterF ( 1 ) can be expressed in words as "the value of f when x is 1." Find or compute Then you practiced interpreting the language related to maximum and minimum values of functions
One was graphed, and the other was in factored form. You used these two pieces of information, without creating a graph of the function in factored form, to determine the maximum value of each one
Be able to find the maximum or minimum of a function by writing the quadratic expression that defines it in vertex form; explain why the vertex is a maximum or minimum when given a quadratic function in vertex form.

What does this chapter state?
- 1F ( 1 ) can be expressed in words as "the value of f when x is 1." Find or compute
- 2That claim is the chapter’s own statement.
- 3Answer from the claim, not from where the chapter sits in the book.
Result: F ( 1 ) can be expressed in words as "the value of f when x is 1." Find or compute
Why. The sentence is taken from this chapter’s summary or key concepts.
Answer with the meaning this chapter gives. A nearby idea from the same book is a different term.
