The number of one one functions f: a b c d
WebFind the number of one-to-one functions f: {a,b,c,d,e} {0,1,2,3,4,5,6,7,8,9} such that f (a) is even or fle) is odd. Do not evaluate expressions such as P (6,3), C (6,3), 7! numerically. Leave them as they are. No marks unless you explain!. Work out the answer on a sheet of paper and submit below. WebAn inverse function essentially undoes the effects of the original function. If f(x) says to multiply by 2 and then add 1, then the inverse f(x) will say to subtract 1 and then divide by 2. If you want to think about this graphically, f(x) and its inverse function will be reflections across the line y = x.
