O4C2 Key Features of Graphs

Does the graph have a maximum or minimum?

• maximum
• minimum
• neither
• both

CCSS.HSF-IF.C.7A

Determine the local maximum.

(Since the graph goes up forever, there is no ABSOLUTE max, but local max just means a maximum you can see)

• Max of -2 and x= -3

• Max of -3 at x = -2

• Max of 3 at x = 1

• Max of 1 at x = 3

Determine the domain of the graph.

• $\left(1,\infty\right)$

• $\left(-\infty,1\right)$
  

• $\left(2,\infty\right)$
  

• (2,5)

CCSS.HSF.IF.B.5

What is the interval of decrease for this function?

(assume the graph continues past the edge)

• (-5, 3)

• (-∞,+∞)

• [-2, 6]

• 
  

  $\left(-2,\infty\right)$

What is the domain of the function?

• 95 to 116 degrees

• 0 to 24

• 0 to 120

• 0 to 24 hours

CCSS.HSF.IF.B.5

What is the absolute maximum?

• 116 degrees at 4 pm

• 120 degrees

• 24 hrs at 100 degrees

• 0 hrs at 120 degrees

What does the absolute maximum mean in context of the graph?

• it's the highest point on the graph

• it's the highest temperature for the day

• it's the biggest number for the day

• It's the most time since midnight.

What is the y-intercept?

• (0,100)

• (100,0)

• (115,0)

• (0,110)

Tags

CCSS.HSF.IF.B.4

What does the y-intercept mean?

• 100 degrees at midnight

• 0 degrees at midnight

• 115 degrees is where it crosses the y-axis

• 110 degrees is where it's exactly on the line
