The explicit formula of a sequence is f (x) = 2x^2 where x Ethe natural numbers. The recursive formula can be written as f(x) = f (x - 1) + 4x + b. what is the value of b?

Which of the following pairs of functions are inverses of each other? o a. f(x)=x72+8 and 96-9 = 7/x+2) =8 o b. f(x)= 6(x - 2)+3 and g(x) - *#2-3 o c. $4) = 5(2)-3 and 90- 4*: 73 o d. f(x) = 6)-12 and 910 – +12

How do you use the elimination method for this question? explain, because i really want to understand!
