In how many ways can you answer a 13 question true-false tests if you answer each question with either a true or false ?

8,192 ways

Step-by-step explanation:

Here in this question, we want to know the number of ways the 13 question can be a answered.

For each question, we have two answers. So what this mean is that each question can be answered in two ways only.

So since each of the questions can be answered in exactly two ways only;

The number of ways the 13 questions can be answered will be ;

2 * 2 * 2 * 2 * * 2 up from the first question to the 13th question.

So the number of ways the 13 questions can be answered is simply 2^13 ways = 8,192 ways

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
