Question
Given the function f(x) = 8 - 3x , solve f(x) = -1
- 3
- 2
- 1
- 0
Hint:
f(x) = 8 - 3x ----------------------------------- Eq 2
f(x) = -1 -------------------------------- Eq 1
From eq 1 and eq 2
We get , 8 - 3x = -1
-3x = -9
x = 3
The correct answer is: 3
To find the value of f(x) = -1 for the function f(x) = 8 - 3x.
Hence the value of f(x) = -1 for the function f(x) = 8 - 3x is 3.
