No. If an input in a function had more than one output, that would be a mapping, but not a function.
By definition. If one input has more than one outputs then it is not a function.
Linear function:No variable appears in the function to any power other than 1.A periodic input produces no new frequencies in the output.The function's first derivative is a number; second derivative is zero.The graph of the function is a straight line.Non-linear function:A variable appears in the function to a power other than 1.A periodic function at the input produces new frequencies in the output.The function's first derivative is a function; second derivative is not zero.The graph of the function is not a straight line.
Yes, square root is one such example: square root of 4 is +2 or -2. The radical symbol (√) is used to denote the positive square root of a number; ie √4 = 2; The square root of a number is thus ±√(the number), eg square root of 4 is ±√4 = ±2.

It is possible.
By definition. If one input has more than one outputs then it is not a function.
A function is any relationship between inputs and outputs in which each input leads to exactly one output. It is possible for a function to have more than one input that yields the same output.
Yes, ( f(x) ) will always be a function if it is defined such that for every input ( x ) in its domain, there is exactly one corresponding output ( f(x) ). A function must satisfy the property that no input can produce more than one output. If this condition is met, then ( f(x) ) is indeed a function. However, if multiple outputs are assigned to a single input, then it is not a function.
Yes, it is possible to get more than one output number for a single input in certain mathematical contexts, such as in functions that are not well-defined or in multi-valued functions. For instance, in the case of the square root function, the input 4 can yield both +2 and -2 as outputs. This ambiguity occurs when the function does not adhere to the definition of a mathematical function, which requires that each input corresponds to exactly one output.
To determine if a relationship is a function, check if each input (or x-value) corresponds to exactly one output (or y-value). If any input is associated with multiple outputs, then the relationship is not a function. A common way to visualize this is by using the vertical line test: if a vertical line intersects the graph of the relationship more than once, it is not a function.
yes
Yes, a function can be represented by a symbol, typically denoted as ( f(x) ), where ( f ) is the name of the function and ( x ) is the input variable. This symbol encapsulates the relationship between the input and output values defined by the function. However, a function itself is more than just a symbol; it embodies a specific rule or formula that describes how to transform inputs into outputs.
Good question. A relation is simply that; any x-value to create any y-value. A function, however, cannot be defined for multiple values of x. In other words, for a relation to be a function, it must have singular values for all x within its domain.
No. A function has only one output per input.
Functions cannot have two y-values (outputs) for any single x-value (input), so if you can draw a vertical line that touches more than 1 point on the graph, it is not a function.
Because a function is defined as having distinct outputs for every input therefore... you can never have two values for one x value and you can see this relationship by drawing a vertical line.
A set of ordered pairs does not represent a function if any input (or x-value) is associated with more than one output (or y-value). For example, the set { (1, 2), (1, 3), (2, 4) } does not represent a function because the input 1 corresponds to both outputs 2 and 3. In contrast, a function would have each input linked to exactly one output.
