Insert three arithmetic means between 25 and 9

21, 17, 13

Step-by-step explanation:

Find the mean of the 2 given values

mean = = = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = = = 21 and

mean = = = 13

Thus the 3 means are 21, 17 and 13, that is

25, 21, 17, 13, 9

(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.
