Question
Given the function k (t) = 2t - 1 , solve k (t) = 5
- 2
- 3
- 4
- 5
Hint:
k (t) = 2t - 1 --------------------------- Eq 2
k (t) = 5 -------------------------------- Eq 1
From eq 1 and eq 2
We get, 2t - 1 = 5
2t = 6
t = 3
The correct answer is: 3
To find the value k (t) = 5 for the function k (t) = 2t - 1.
The value k (t) = 5 for the function k (t) = 2t - 1 is 3.
