Which of the following are geometric sequences?

1 answer:

6 0

A. 2,-2,2,-2,2,-2,2
C. 10,5,2.5,1.25,0.625,0.1325
and
D. 1,2,4,8,16,32
Are all geometric sequences

This means that each sequential # is derived by either multiplying or dividing by a number.

For instance, A. is found by multiplying each by - 1, B. is found by multiplying each by 1/2 (0.5), and D. is found by multiplying each by 2

Answer: f(x)= $0.5^x$ has all real value as its domain.

Explanation: since, we have three functions f(x)= $0.5^x$ ,

while g(x) and p(x) are line segments.

Now, g(x) is a function by a line segment which passes through two points (-1.8,-3) and ( 1,3.8).

Thus it is clear that its domain will be the ends points. so domain of the function g(x) will be [-1.8, 3.8] which is the subset of real numbers set (R).

Similarly, domain of function p(x) will be [1.7, 1], which is also the subset of R.

But, when we talk about f(x) it contains all the possible value of x. Thus we can say that $f(x)= 0.5^x$ has R as its domain.
