2.) True or False? When working with a function, substituting a certain value of x into the formula gives only one value of y for that value of x.

TRUE

Step-by-step explanation:

In a function, every domain value (x-value) must have exactly one corresponding range value (y-value). This means that in a function, an x-value or input value cannot have two different y-value or output value. Or else, it ceases to be a function.

So, when you substitute a certain value of x into the equation of a function, you can only have one exact value of y for that value of x.
