To solve for F ( x ) = 2 when F ( x ) = 3 x − 1 , we need to find the value of x that makes the equation true. Here’s how we can do it step-by-step:
Write down the given function equation :
F ( x ) = 3 x − 1
Set the equation equal to 2 :
3 x − 1 = 2
Solve for x by isolating it :
a. Add 1 to both sides to eliminate the − 1 on the left side:
3 x − 1 + 1 = 2 + 1 3 x = 3
b. Divide both sides by 3 to solve for [tex]x[/tex]:
x = 3 3 x = 1
Conclusion : The solution set for F ( x ) = 2 is { 1 } .
Therefore, the correct multiple-choice answer is option A: { 1 } .
