Evaluate the function for the following input:

f(x)=3 - 2x. Which input generates the largest output when evaluating the function?

A. f(0)
B. f(3)
C. f(5)
D. f(2)

To evaluate the function, we substitute the input value into the function expression and calculate the output.

For option A, f(0) = 3 - 2(0) = 3.
For option B, f(3) = 3 - 2(3) = 3 - 6 = -3.
For option C, f(5) = 3 - 2(5) = 3 - 10 = -7.
For option D, f(2) = 3 - 2(2) = 3 - 4 = -1.

We can see that the largest output is generated when evaluating the function using option A, f(0), which gives an output of 3.

Therefore, the correct answer is option A.
