Now take each of the answers you
got and write them in one of the
boxes on you BINGO card. Use
must be completely filled in order
to play the game. If you didn’t
finish a question, then put an “X”
in a box. That box won’t be used
to play the game. Put your name
on your paper and turn it in now!
An answer will appear on the screen. If
a check mark on it. Once you get 5
answers in a row marked, call out
verified you will receive a prize. ALL
ANSWERS MUST BE WRITTEN THE WAY
THEY APPEAR ON THE SCREEN TO BE
CORRECT. (ex. X=3 not just 3)
(1,7)
Y = (x + 3)&sup2; - 14
(-∞, 6]
X = 0 , -4
( -∞, +∞)
X=7
( 5x + 3)( x – 1 )
( -∞, 1)
X = &plusmn; 2i
( -4,+∞)
Y = -2x&sup2; + 8x - 12
+∞
+∞
X = -5
Min Value = -3
@ x =-4
x&sup2; + 6x +7
Y = (x + 1)&sup2; - 5
Negative
B
X &lt; -&frac12; or x &gt; 3
Yes, it is a
solution
X = &frac12;, 7
