We are given the function and asked to evaluate it for some given values. x=1, 2, 3This means that we should substitute 1, 2, and 3 for x in the given expression and then evaluate. Let's start with 1.
3-2^x
3-2^1
3-2
1
Now, let's do the same thing for the rest of the values.
Input, x 3-2^x Output, y
1 3-2^1 1
2 3-2^2 -1
3 3-2^3 -5
