, c) Both sequences are arithmetic.
Step-by-step explanation:
a) The sequence of natural numbers which are multiplied by 3 are represented by the function ,
. Let see the first five elements of the sequence: 3, 6, 9, 12, 15,...
b) The sequence of natural numbers which are multiplied by 3 and added to 1 is represented by the function ,
. Let see the first five elements of the sequence: 4, 7, 10, 13, 16,...
c) Both sequences since differences between consecutive elements is constant. Let prove this statement:
(i)
(ii)
Both sequences are arithmetic.
Answer:
Step-by-step explanation:
To find the inverse of the function , the first step is to replace f(x) with "y":
The second step is to solve for the variable "x":
The third step is to interchange the variables, then:
Finally, let be h(x) the inverse of the function f(x). Then, you can replace "y" with h(x). Therefore, this is:
