How many tiles are needed to build Step 6

• 32

• 45

• 60

• 77

Identify the factored form of the equation for the graph.

• f(x) = (x - 3)(x + 1)

• f(x) = (x + 3)(x - 1)

• f(x) = (x - 4)(x + 1)

• f(x) = (x + 4)(x - 1)

Identify the standard form for the equation for the graph:

• f(x) = (x - 1)² + 3

• f(x) = (x - 1)² - 3

• f(x) = (x + 1)² - 4

• f(x) = (x - 1)² + 4

Give the range for the function:

• All real numbers

• f(x) > 0

• f(x) > -4

• f(x) < -4

• 2

• -2

• ½

• -½

• -1

• The vertex is shifted right from orgin

• The vertex is shifted up from orgin

• The vertex is shifted down from orgin

• The vertex is shifted left from orgin

Create the vertex form for the function

y = x² - 10x + 32 by completing the square. Which of the following is the correct vertex form?
