this question. First assess. If this scrap represents a function, we can determine this by using the vertical line test. As you can see, no matter where we draw a vertical line, the Graf will only intersect this line once. So it must be true that this is a function. Now we need to define the domain of this function that's gonna be equal to any real number. So the domain is that X is an element of all real numbers. Not to find the range of this function, as you could see from the graph, why can never be unless the negative one. So the range of this function is why it's more than or equal to negative one.

The number 2 is also the smallest & first prime number (since every other even number is divisible by two).
