If f(1)=2f(1)=2 and f(n)=f(n-1)^2-n

then find the value of f(4)

Given that and

We need to determine the value of f(4)

To determine the value of f(4), we need to know the values of the previous terms f(2), f(3).

The value of f(2):

The value of f(2) can be determined by substituting n = 2 in the function

Thus, we get;

Thus, the value of f(2) is 2.

The value of f(3):

The value of f(3) can be determined by substituting n = 3 in the function

Thus, we get;

Thus, the value of f(3) is 1.

The value of f(4):

The value of f(4) can be determined by substituting n = 4 in the function

Thus, we get;

Thus, the value of f(4) is -3.

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
