Question

2 quick algebra 1 questions for 50 points! Only answer if you know the answer, Tysm!

Answer 1

Yes

As per definition

Every domain of the function has an unique range

• f(x)=y

Here

• f(-8)=1
• f(-2)=6
• f(0)=4
• f(7)=5

Hence it's a function

Answer 2

Answer:

QUESTION 1:  (-3,0), (1,1), (5, 2), (9,3)

QUESTION 2: Draw a mapping diagram (see question 3)

QUESTION 3: Yes, the image below is a function.

Step-by-step explanation:

For question 1, you can pair the domains (x-values) with any y-value. The y-values can repeat.

For question 3b, you must understand that domains cannot repeat, but ranges (y-values can). In 3b, every x-value has a unique y-value which means that it is a function. You can also determine is something is a function by seeing if its graph passes the vertical line test.
