Question

a function is a rule that assigns each value of the variable to exactly one value of the dependent variable

Answer 1

Let's imagine that we have the following function function:

$y = x ^ 2$

We have to:

Independent variable: x

Dependent variable: y

For x = -1:

$y = (- 1) ^ 2 = 1$

For x = 1:

$y = (1) ^ 2 = 1$

We observe that the independent variable can only obtain one result.

Answer:

TRUE
