Answer:
If the graph of a function f is known, it is easy to determine if the function is 1 -to- 1 . ... If no horizontal line intersects the graph of the function f in more than one point, then the function is 1 -to- 1 . A function f has an inverse f−1 (read f inverse) if and only if the function is 1 -to- 1 .

9 x 3 = 27
4 x 3 = 12
ratio- 9 : 4 = 27 : 12

In this question we are asked to find the ratio of the number of chocolates which Lauren liked and the total of chocolates.
We know she doesn't like coconut and toffee, so she likes caramel, mint and cherry. When we count the ones she liked, we got

.
When we add to find how many chocolates are there, we got

.
To find the ratio we need to divide the first one and the second one:

is our probability.
