A sequence is defined by f(1) =3 and f(n) =2 x f(n-1) for n > 1. Which of the following statements defines the nth term of f. a. f(n) = 3 x 2n for n > 1
b. f(n) = 3 x 2n-1 for n > 1
c. f(n) = 3 + 2(n-1) for n > 1
d. f(n) = 3 + 2n for n > 1

answer.A.f(n)=3×2n for n/1

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

-2 is the right
