Which choice shows a function with a domain of {–4, –2, 2, 4}? On a coordinate plane, a vertical line is at x = 2. On a coordinate plane, a line goes through (negative 2, negative 2) and (0, negative 3). {(–4, 2), ( –2, 1), (2, 0), (4, 5)} {(1, –4), (0, –2), (2, 2), (6, 4)}

Step-by-step explanation:

Given: Domain of function is

To find: the function that has domain

Solution:

A function is a relation in which every element of the domain has a unique image in the co-domain.

For x = 2, domain is

For a line that passes through ,

domain must have 0 but

Domain of is

Domain of is

So, answer is

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

what grade level is this? need to know so i can look in my old textbooks!
