Lesson 4: Analyzing Graphs

Question 1

Determine the x-intercepts of the function. Check all that apply.

Revolt · Accepted Answer

(–2, 0); (0, 0)

Question 2

Determine the intercepts.

Revolt · Accepted Answer

✔ (–1, 0); x-intercept =: (–1, 0); y-intercept =: (0, 2)

Question 3

(–2, –14) (–1, 0)✔ (0, 2)(1, 4)

Revolt · Accepted Answer

✔ (0, 2)

Question 4

Use the graph to find the local minimum and the local maximum for the given function.

Revolt · Accepted Answer

Over the interval [–3, 0], the local minimum is .: –16.18; Over the interval [0, 3], the local maximum is .: 3.75; Over the interval [0, 3], the local minimum is .: –3

Question 5

0–16.18-3✔ 3.75

Revolt · Accepted Answer

✔ 3.75

Question 6

0–16.18–3.75✔ –3

Revolt · Accepted Answer

✔ –3

Question 7

Which statement is true about the given function?

Revolt · Accepted Answer

f(x) < 0 over the intervals (–, –2.7) and (–1, 0.8).

Question 8

Use the graph to determine which statement is true about the end behavior of f(x).

Revolt · Accepted Answer

As the x-values go to negative infinity, the function’s values go to positive infinity.

Question 9

Which intervals show f(x) decreasing? Check all that apply.

Revolt · Accepted Answer

[–2.5, –2]; [–2, –1.5]; [1.5, 2]; [2, 2.5)

Question 10

Analyze the function’s graph to determine which statement is true.

Revolt · Accepted Answer

Over the interval [–2.5, 0.5], the local maximum is 2.
