you can tell if there is an independent (x) and a dependent (y) variable
yes.
A relation is a function if every input has a distinct output.
relation and function are number that combine with number and neqative number to .
Because a function has additional restrictions, which the relation may, or may not, satisfy.
Function is a special case of relation. It means function is a relation but all relations are not functions. Therefore all functions are relations.
A relation is a function when an x value only has one y value associated with it. An easy way to tell this is to graph the relation, then draw a vertical line through it. If, at any point, it touches the graph twice, the relation isn't a function.
Not every relation is a function. But every function is a relation. Function is just a part of relation.
no i dont think so:(
A relation is a function if each input (or domain value) is associated with exactly one output (or range value). To determine this, you can check if any input value appears more than once in the relation; if it does, the relation is not a function. Additionally, in a graph, a relation is a function if it passes the vertical line test—if any vertical line intersects the graph at more than one point, it is not a function.
No, a function must be a relation although a relation need not be a functions.
Does the graph above show a relation, a function, both a relation and a function, or neither a relation nor a function?
A function is a relation whose mapping is a bijection.
yes.
Not every relation is a function. A function is type of relation in which every element of its domain maps to only one element in the range. However, every function is a relation.
No. A relation is not a special type of function.
A relation is a function if every input has a distinct output.
