Juan starts a new coffee shop. the table shows the coffee sales at his shop for the first 5 days.

what is the average rate of change in the sales per day between the 2nd and 5th day?

$30/day

Step-by-step explanation:

average rate of change = (s(b)-s(a))/b-a

where s(b) =$310

s(a) = $220

b= 5

a= 2

average rate of change = (310-220)/(5-2)

average rate of change =  90/3

average rate of change = $30/day

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

hi how are you doing today? if you ever need just tell me
