To find: To describe is a graph that consists of a single point the graph of a function? And write the equation?
Answer to Problem 40AYU
The point of the graph of a function is
The equation is
Explanation of Solution
Given information: Single point graph
Calculation:
1stpart Yes,
Since, every input in the domain has exactly one output a single point is a function.
For example:
Let us choose point
That means
Hence, the point of the graph of a function is
2ndpart Let, a single point
We can write an equation
Hence, the equation is
