(1,-2) as a function notation

Sagot :

Given:

The point is (1,-2).

To find:

The function notation of the given point.

Solution:

If a point is (x,y), then its function notation is f(x)=y.

The given point is (1,-2).

Here, x-coordinate is 1 and y-coordinate is -2. So, the function notation of the given point is

[tex]f(x-coordinate)=y-coordinate[/tex]

[tex]f(1)=-2[/tex]

Therefore, the function notation of the given point (1,-2) is f(1) = -2.
