Let p={6,7,8,9,10}, q={7,8,9}, and r={3,4} find p∪q a. {3,4} b. {7,8,9} c. {6,7,8,9,10} d. ø empty set

I think your answer is D

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
