Function Notation Exit Ticket

A function is a relation where each input (x-value) has exactly one output (y-value).

If every input is connected to only one output, then it is a function.

It means the relation is not a function.

f(1) = 2(1) + 3 = 5.

Function notation is a way to represent functions using symbols, typically f(x), where 'f' is the function name and 'x' is the input.

Set the function equal to k and solve for x.

A visual way to determine if a graph represents a function; if a vertical line crosses the graph more than once, it is not a function.

f(0) = -0 + 4 = 4.

The domain is the set of all possible input values (x-values) for the function.

The range is the set of all possible output values (y-values) for the function.
