ANSWER:
y is a function of x and the function is a one-to-one function.
Step-by-step explanation:
Given:
To:
Determine whether y is a function of x and if the function is one to one
Recall that, for a relation to be termed a function, each input value (x-value) must have exactly one output value(y-value).
Looking at the given table, we can see that each x-value is mapped to exactly one y-value, therefore, we can say that the relation is a function.
To determine if a function is a one-to-one function, every y-value must have exactly one corresponding x - value.
Looking at the table, we can also see that every y-value is mapped to exactly one corresponding value of x, so the function is a one-to-one function.
Therefore, we can say y is a function of x and the function is a one-to-one function.
