Domain, Range & Function Values

See attachment.

Question 8

f(-1) = 4
f(0) = 3
f(1) = 6
f(3) = 0

Domain = [-1, 3]
Range = (-00, 7]

You say?

Question 10

f(-2) = -3
f(1) = 0
f(0) = 1
f(2) = -2

Domain = [-1, 1]
Range = (-00, 1] U [1, 00)

You say?

 

The domain is the set of all the values of x.
The range is the set of all the values of y.

Question 8

f(-1) = 4
f(0) = 3
f(1) = 6
f(3) = 0

you have ordered pairs (x,y)=> (-1,4), (0,3), (1,6), (3,0)

Domain => all x values: [-1,0,1, 3]
Range => all y values: [0, 3,4,6]



Question 10

f(-2) = -3
f(1) = 0
f(0) = 1
f(2) = -2

Domain = [-2, 1.0,2]
Range = [-3, -2,0,1]

 

You said:

"The domain is the set of all the values of x."

How did you arrive at this conclusion?

You said:

"The range is the set of all the values of y."

How did you arrive at this conclusion?

Note:

I will also do 7 and 9 for extra practice.

 

practice makes progress

 

I posted questions 7 and 9 in a new thread.
