Somebody pls answer

write the first four terms of the function f(n)=n^2-1

0,3,8,15

Step-by-step explanation:

f(n)=n^2-1

The first term is

f(1) = 1^2 -1 = 1-1 =0

The second terms is

f(2) = 2^2 -1 = 4-1 = 3

The third term is

f(3) = 3^2 -1 = 9-1 =8

The fourth term is

f(4) = 4^2 -1 = 16-1 =15

168

step-by-step explanation:

i am pretty sure that the answer is 168

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
