Section 2.0 Review/Group Assignment #1
Answer Key
1. The equation is y   x 1
2. 6. The graph should look like this:
3. The solution is
x  15313
.
y  0.7188
Note that one may choose to write this data as a point. That is, as (1.5313,0.7188).
49 23 I
F
G
H32 , 32 J
Kis also acceptable (perhaps even preferable.)
4. This graph should look like this:
5. The vertex is (0.75, -3.125)
and the graph should look like this:
6.
 b  b 2  4ac
) we get x  2 or –1.
2a
b. First rewrite the equation in the for ax 2  bx  c  0 and then apply the quadratic
formula to get x  2.3028 or 1.3028.
a. Using the quadratic formula ( x 
c. Upon trying to rewrite this you will be left with the solution x  0 .
7. Plug the points into the equation or inequality and choose those which result in a “true
statement.”
a. (1,2)
b. (2,0) and ( 2 , 2)
c. (1,-2), (5,1), and (2,-3)
