To solve a function, you need to understand the mechanism. A function is like a microwave, you put something in it, and something will come out. So, an input and an output. For example f (x) = x + 1, given x is 7. You would insert 7 into the equation, f (7) = 7 + 1, which is 8. So the input is 7, resulting in an output of 8.Whether you’re receiving strange phone calls from numbers you don’t recognize or just want to learn the number of a person or organization you expect to be calling soon, there are plenty of reasons to look up a phone number.The set of real numbers is denoted R or [2] and is sometimes called "the reals".
