How would you evaluate and substitute this problem.
For which of the following functions f is f(x)=f(1-x) for all x?
This is just a little too long ago for me to remember. I just need to see how you substitute and evaluate. If you could work it out so I could see, that would be epic win. Thanks guys.
I think what dapefley is saying is that the question was to determine which of several given functions (which he apparently does not remember) satisfies f(x)=f(1-x) for all x and that the "correct" answer was then given as .
You determine that by doing what it says and seeing if the equation is true. In particular you find f(1- x) by replacing the "x" in the formula by 1-x: so . Of course, 1-(1-x)= 1-1+x= x so .
