Answer:
option (b) is correct.
The value of 
is 0.
Step-by-step explanation:
Given: 
and 
We have to find the value of
Consider the given function
First evaluate value of function f(x) at x = 3 and 1 then substitute it in .
f(3) = 1 + 3 = 4
f(1) = 1 + 1 = 2
Substitute, we get
Solving further , we get,
Now evaluate at t = 0 , we get,
Thus, value of is 0.
Thus, option (b) is correct.

x< 15 where x is the average that each person contributes.
This gives 3x <45, limiting the gift basket's total cost to < $45. (Actually ≤ 14.99 per person, so max cost is $44.97.
19. simple algebra
a <= -4 + 7
a <= 3
20.
since u divide and the co efficient is negative u flip the sign
-3m<15
m>-5
There is an infinite number of values that are in both the domain and range.
Multiply the decimal by 100. Then add the % sign.
There is only one square root of any number that has one. The square of 196 is 14 because 14 x 14 = 196.
