QOTD Catch-up

Friday, 10/2/2015

I have fallen behind on the Analytic Geometry Question of the Day, so here are four questions to help us catch back up (notice: Question # 4 has four equations and four solutions to match to those equations).  I know of at least one family that has been working on the QOTD and will turn the first 10 in for the aforementioned points.

#1   What are the solutions to the equation ?

a. x = - 27 only

b. x = 75 only

c. x = - 27 and x = 75

d. x = - 75 and x = 75

# 2   Use the graph of the function g(x) to answer the question.

Which statement about the real solutions of g(x) is true?

a. g(x) has no real solutions. 

b. g(x) has exactly one real solution.

c. g(x) has two real solutions that are rational

d. g(x) has two real solutions that are irrational

# 3    Use the quadratic formula to find the roots of the quadratic equation.

 

a. 

  b. 

 

c. 

 

d. 

# 4    Match the items.

The task is to match the lettered items with the correct numbered items. Appearing below is a list of lettered items. Following that is a list of numbered items. Each numbered item is followed by a drop-down. Select the letter in the drop down that best matches the numbered item with the lettered alternatives.

a. x = -1
b. x = -1 and x = 2/3
c. x = -½      and x = 3
d. x = -5
1. x2 + 2x + 1 =0	a  b  c  d
2. x2 + 10x + 25 = 0	a  b  c  d
3. 6x2 + 2x – 4 = 0	a  b  c  d
4. 8x2 – 20x – 12 = 0
