**javascript Are two functions equal? - Stack Overflow**

Injective means we won't have two or more "A"s pointing to the same "B". So many-to-one is NOT OK (which is OK for a general function). As it is also a function one-to-many is not OK... Horizontal Line Test. A test use to determine if a function is one-to-one. If a horizontal line intersects a function's graph more than once, then the function is not one-to-one. Note: The function y = f …

Injective means we won't have two or more "A"s pointing to the same "B". So many-to-one is NOT OK (which is OK for a general function). As it is also a function one-to-many is not OK... Since not all columns are pivot, we do not have uniqueness, and the transformation T is not one-to-one. In fact, we do not even need to make any computation in order to show T is not one-to-one, since the solutions to the corresponding 4 equations in 6 variables cannot be unique (see the numerical consequence of uniqueness).

**How to determine whether a function is one-one or many-one**

6/07/2007 · A one-to-one function passes both the horizontal and vertical line tests. If a function is one-to-one then for each x value there is one and only one corresponding y value.... X has to have exactly one Y value. You can't have two Y values and you can't have no Y values. So that's something to keep in mind. It has to have exactly one Y value. So let's look at a couple of examples. A lot of times you guys see math information organized in a table. Here I have my X numbers, 8, 9, 10 and 13. That's kind of weird. Don't be freaked out. Sometimes math numbers are

In general, though, if one composition gives you just "x", then the other one will, too, especially if you're not dealing with restricted domains. But you should remember to do both compositions on tests and such, in order to get full credit.... One would express the functions in 'y =' form, set the right side of these forms equal to each other, solve for x, (or x's), and use this x, (or x's), to find the corresponding y, …

## How To Tell If Two Functions Are One To One

### A function f is 1 -to- 1 if no two elements in the domain of f correspond to the same element in the range of f . In other words, each x in the domain has exactly one image in the range. And, no y in the range is the image of more than one x in the domain. If the graph of a function f is known, it

- How do you know if a quadratic equation will have one, two, or no solutions?. The short answer is, it is easy: They all have two solutions. The Fundamental Theorem of Algebra guarantees it. Now if what you really meant to ask is: How do you know if a quadratic equation will have one, two, or no solutions over the real numbers, then read on. A quadratic equation of the form: has a general
