Answer: Yes, that is correct.
The ordered pair (1,-2) can be written using function notation as f(1) = -2.
The first number in the ordered pair, 1, is the input value and the second number, -2, is the output value. The function notation f(x) is used to indicate that the output value is a function of the input value x.
In this case, f(1) = -2 means that when the input value is 1, the output value is -2. This can be represented as a point (1,-2) on the coordinate plane.
