2. NO INVERSE
REMEMBER:
- An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing.
Example of inverse function:
- f-1(11) = (11-3)/2 = 4. And then:
- f(4) = 2×4+3 = 11. So we can say:
- f( f-1(11) ) = 11. "f of f inverse of 11 equals 11"
