Guided Practice – #9
Find coordinates of
x
-intercepts, y-intercept, and maximum or minimum points on the graphs of these quadratic functions.
f(x) =
x
(7 –
x
)
f(x) = -
x
(7 –
x
)
f(x) = (x-3) (x-8)
f(x) = -2(x – 3)(x – 8)Slide10
Guided Practice – #10
Write rules for quadratic functions with graphs that meet these conditions:
x
-intercepts at (-2, 0) and (6, 0) with graph opening upward
x
-intercepts at (2, 0) and (6, 0) with minimum point at (4, -8)
x-intercepts at (-2, 0) and (6, 0) with y-intercept at (0, -60)Slide11
Extra PracticeSlide12
Let’s Play some Musical Chairs!
There are
5 stations
around the classroom with a quadratic equation
When I say go, you have
30 seconds
to take your worksheet and pencil and move to
one station
Once everyone is at a station, the music will begin playing and you will need to spend the
duration of the song
trying to find the
important key points
When the
music stops
, you must stop writing
immediately
and go to the
next station
When we are finished with 5 songs, you will be given the opportunity to
finish
your graphs with
one last song Slide13
