What is the range and domain of the function {(2,5),(8,3),(1,5),(7,9)}

In general for a point we have (in, out)

The domain is the set of all the 'in's and the range is the set of all the 'out's

Domain: {2, 8, 1, 7} or {1, 2, 7, 8} in order

Range: {5, 3, 9} or {3, 5, 9}

Sets do not contain duplicates so 5 appears only once.

32

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
