Given a real number x and a positive integer k, determine the number of multiplications used to find k x 2 starting with x and successively squaring (to find x2 , x4 , and so on). Is this a more efficient way to find k x 2 than by multiplying x by itself the appropriate number of times?

16.9 times 2.85

step-by-step explanation:

(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.
