The IF function in Excel can be nested, when you have multiple conditions to meet. Explanation: if the score equals 1, the nested IF formula returns Bad, if the score equals 2, the nested IF formula returns Good, if the score equals 3, the nested IF formula returns Excellent, else it returns Not Valid. If you have Excel , simply use the IFS function.
Explanation: if the score is less than 60, the nested IF formula returns F, if the score is greater than or equal to 60 and less than 70, the formula returns D, if the score is greater than or equal to 70 and less than 80, the formula returns C, if the score is greater than or equal to 80 and less than 90, the formula returns B, else it returns A. Many examples and complete solutions to the problems are shown, so the readers can study at home. I believe that the book containing many exercises and their solutions  is quite useful not only for the students, but also the p- fessors.

Tom 5. Who does he go to? What if nobody is five-foot-five? What if there are six people in the room that are five-five?
Do they all have to pay? What if you are five-foot-five?
And what if you're out of cash? And allergic to anchovies? Are you still on the hook?
What a mess! The relation "height indicates name" is not well-behaved. It is not a function. For a relation to be a function, there must be only and exactly one y that corresponds to a given x. Here are some pictures of this:.
Now YOU try! The "Vertical Line Test".
This characteristic of non-functions was noticed by I-don't-know-who, and was codified in "The Vertical Line Test": Given the graph of a relation, if you can draw a vertical line that crosses the graph in more than one place, then the relation is not a function. Here are a couple examples:. Think of all the graphing that you've done so far. In other words, if you can enter it into your graphing calculator, then it's a function.
The calculator can only handle functions. Do you take the positive square root, or the negative? So, in this case, the relation is not a function. You can also check this by using our first definition from above. Stapel, Elizabeth.
