46 answer quickly and with full reponce and show ur 2. a pool company is trying out several new drains. drain a empties a pool at a rate of 2 gal/min. drain b empties a pool at a rate of 5 gal/min. one pool has 108 gal of water in it. write an equation for each drain that shows the amount of time it takes to empty the pool. then solve each equation showing your work.   2. the three salespeople for a local advertising firm are lola, ahmed, and tommy. lola sold $2030 in ads, ahmed sold $1540, and tommy sold $1800. (a) what fraction of the total sales did each salesperson sell? (b) a $100 bonus was awarded to the three salespeople, which they had to share. it was awarded so that each salesperson received the same fraction of $100 as he or she sold of the total sales. how much did each person receive? round to the nearest whole cent.

when functions are first introduced, you will probably have some simplistic "functions" and relations to deal with, usually being just sets of points. these won't be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. small sets of points are generally the simplest sorts of relations, so your book starts with those.

step-by-step explanation:

state the domain and range of the following relation. is the relation a function?

{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}

the above list of points, being a relationship between certain x's and certain y's, is a relation. the domain is all the x-values, and the range is all the y-values. to give the domain and the range, i just list the values without duplication:

domain: {2, 3, 4, 6}

range: {–3, –1, 3, 6}

(it is customary to list these values in numerical order, but it is not required. sets are called "unordered lists", so you can list the numbers in any order you feel like. just don't duplicate: technically, repetitions are okay in sets, but most instructors would count off for this.)

while the given set does indeed represent a relation (because x's and y's are being related to each other), the set they gave me contains two points with the same x-value: (2, –3) and (2, 3). since x = 2 gives me two possible destinations (that is, two possible y-values), then this relation is not a function.

note that all i had to do to check whether the relation was a function was to look for duplicate x-values. if you find any duplicate x-values, then the different y-values mean that you do not have a function. remember: for a relation to be a function, each x-value has to go to one, and only one, y-value.

state the domain and range of the following relation. is the relation a function?

{(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)}

i'll just list the x-values for the domain and the y-values for the range:
