Which functions are Invertible Choose each correct answer

BaLLatris [955]3 years ago

Answer: Top right and top left.

Step-by-step explanation:

For a function to be invertible, we must have that the function is one to one, this is because if we have that the function f(x1) = Y = f(x2)

for the inverse, such that g(f(x1)) = x1

but we know that f(x1) = f(x2)

this means that g(f(x1)) = x2

so g(y) is not a function.

Then, the only functions that can be invertible are the one-to-one functions, the top right, and the top left functions.
