Hoped it helped :D
Answer:
(a)


(b)


(c)


Step-by-step explanation:
(a) This is a sequence of consecutive number



(b) This is a sequence of 2 to the power of n - 1. The next number is twice time of this number



(c) This is factorial sequence. Where the next number is this number multiplied by 



C is FALSE
the set of whole numbers is { 0, 1, 2, 3, 4 , ......}
the set of integers is { ..., - 2, - 1, 0, 1, 2, 3, ......}
As we can see the set of whole numbers does not include negative numbers, thus integers are not a subset of whole numbers
However, whole numbers are a subset of integers.
Answer:
y = 5 cos ((2π/3)x - 2) + 2
Step-by-step explanation:
Cosine function takes a general form of y = A cos (Bx + C) + D
Where
A is the amplitude
2π/B is the period
C is the phase shift ( if -C, then phase shift right, if +C phase shift left)
D is the vertical displacement (+D is above and -D is below)
Given the conditions of the function to build and the general form, we can write:
** Note: period needs to be 3, so 2π/B = 3, hence B = 2π/3
Now we can write:
y = 5 cos ((2π/3)x - 2) + 2
first answer choice is right.
