Bellwork – Unit 11 – Day 3
1. Mark the correct relationships
Zeros Initial Value Max/Min
(x+3)(x-1)
(x+12)^2 +5
x^2 +4x + 6

2. Is the function increasing or decreasing over each of the following intervals?

Increasing Decreasing
-3 < x < -2
-2 < x < -1
0 < x < 2

3. Complete the table below.
Statement Reason
5(n+1) = 2(n+10) Given
5n +5 = 2n + 20
3n + 5 = 20
3n = 15
n = 5

4. Use the function, f(x)= 2x^2+3x-2 to find f(2).

5. Change the following into vertex form: (x-h)^2 + k
x^2 + 6x + 2 = 0
