Answer:
f(n) = -8 -3(n -1)
Step-by-step explanation:
The given recursive formula tells you that the difference between two sequential terms is -3, and that the first term is -8. This is a formula for an arithmetic sequence, so we can use the explicit formula ...
f(n) = a1 +d(n -1)
for a1 = -8 and d = -3.
f(n) = -8 -3(n -1)
Answer:
she can buy 6 dolls
Step-by-step explanation:
hello :
(-2)-(2) =(2)-(6)=(6)-(10)=-4 (common diffrence)of aritmetic sequence
a recursive formula for the <span>sequence is : An+1=An-4
</span><span>next term is : (-2)+(-4) = -6</span>
Here is how we get the answer....
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
