WebFeb 23, 2015 · For a relation to be a function, no input (x-value) may be repeated, i.e., have two or more outputs (y-value). Since 3, 6, 7, and 9 have been used as inputs, select either 8 or 12 for the x-value. ... That's because a function can only have one y value for each x value, so you can't repeat the same x value. So either 8 or 12 for x should work ... WebJust like a relation, a function is also a set of ordered pairs; however, every x x -value must be associated to only one y y -value. Suppose we have two relations written in tables, A …
why can
A function can have repeating y values. This happens when two inputs (x values) lead to the same output (y value). This does not violate the definition of a function, which is a relation where each input has only one output. A repeating y value means we have an output that has more than one corresponding input. … See more A y value can be repeated two or more times for a function. However, any function with repeated y values is not one-to-one. A single y value can be repeated up to n times for a … See more Now you know that a function can have repeating y values – but a one-to-one function cannot. You also have some examples to help illustrate the difference between the two types of functions. I hope you found this article … See more WebNo. A function, by definition, can not have multiple outs for a specific input value. Each input can create only one output to be a function. Thus, any equation that doesn't meet this definition would not be a function. ... It … chalk in portuguese

WebLet’s first take a closer look at how the function f(x) = (x2 − 4) / (x − 2) behaves around x = 2 in Figure 2.2.1. As the values of x approach 2 from either side of 2, the values of y = f(x) approach 4. Mathematically, we say that the limit of f(x) as x approaches 2 is 4. Symbolically, we express this limit as. WebDec 18, 2012 · Yes. As long as there is only 1 value for each argument, it is a function. For example, the range of the sine function (y = sin x), for real values of x, consists of all the real numbers from -1 to 1 inclusive, and this range repeats infinitely many times. But for each value of x, there is only 1 value of sin x. Wiki User. ∙ 2012-12-18 19:21:22. WebNov 17, 2024 · Identify the input values. Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
