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

Its due ! write an equation in which the quadratic expression 2x^2-2x 12 equals 0. show the expression in factored form and explain what your solutions mean for the equation. show your work.

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.
