Final answer:
To find the value of the input when the output of the function is 11, we solve the equation 2x - 1 = 11.
Step-by-step explanation:
To find the value of the input when the output of the function is 11, we can set up the equation:
2x - 1 = 11
Solving for x, we add 1 to both sides:
2x = 12
Then divide both sides by 2:
x = 6
