Finding Extrema

Common Core II – Day 2Slide2

Warm Ups

a) Factor to solve the equation x

2

– 7x + 10 = 0.

b) Explain what the solutions tell you about the graph.

c

) Using what you know about the quadratic function, draw a rough sketch.Slide3

We will do some examples as a class and the rest is homework:

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
