QUIZ

start

0 < x < 3

0 < x < 3

All Real Numbers

What is the domain of the function?

question 1/5

QUIZ

Explanation:You ALWAYS need to check for open circles versuses closed circles on the numbers you got after cropping your image. Also, domain means x-values, so you need to draw your lines DOWN through the x-axis in order to see what needs are needed.

QUIZ

RIGHT!

QUIZ

1 < y < 4

-3 < y < ∞

1 < y < ∞

What is the range of the function?

question 2/5

Explanation: Range means y-values; therefore, you need to draw your lines to the RIGHT, so you see what number(s) on the y-axis you need. Lastly, arrows mean infinity and since the arrow is going up forever we are approaching positive infinity.

QUIZ

D: -∞ < x < 2R: ℝ

D: ℝR: -∞ < y < 2

D: -∞ < x < 2R: ℝ

What is the domain AND range of the function?

QUESTION 3/5

Explanation:Domain means x-values and Range means y-values. With the Domain, there is a definite stopping point at 2 and the arrows on the functions go forever left AKA -∞. The Range has NO stopping point in either direction; therefore, it will touch EVERY SINGLE y-values, so the answer is all real numbers (ℝ).

QUIZ

RIGHT!

QUIZ

Yes, because the graph fails the vertical line test.

No, because the graph fails the vertical line test.

Yes, because the graph passes the vertical line test.

Is the following relation a function? Explain.

QUESTION 4/5

Explanation: The relation is NOT a function because it fails the vertical line test. Meaning that any vertical line you draw through the relation hits it MORE THAN ONCE.

QUIZ

RIGHT!

QUIZ

D: -2 < x < 3R: 1 < y < 5 Yes, it is a function.

D: -2 < x < 3R: -2 < y < 5 Yes, it is a function.

D: -2 < x < 3R: -2 < y < 5 Yes, it is a function.

State the domain and range. Then identify if the relation is a function.

QUESTION 5/5

Explanation: ALWAYS crop your picture first. Draw your lines DOWN for DOMAIN and to the RIGHT for RANGE. Doing this ensures that you won't accidentally cut off a part of the graph unintentionally. After that check for open and closed circles to ensure that you are using the correct inequality symbols.

Ranges means all the y-values

Output means x-values

Domain means all the y-values

Input means y-values

You can drag the light to search through the darkness

CLICK ONLY ON THE CORRECT STATEMENT 1/3

Correct!

Given f(-2) = 3, 3 would be labeled as the x-value.

In order to be a function, the x-value CAN'T repeat.

Given f(-2) = 3, the corresponding ordered pair would be (3, 2)

The y-value comes first in an ordered pair.

In order to be a function, the y-value CAN'T repeat.

< means closed circle

Arrows to the right mean ∞

Arrows to the left mean ∞

Arrows up mean -∞
