Question

The ordered pair belongs to the function y= f(x), express the pair using function notation. (2, -2)f(_) =

Answer 1

If the ordered pair (a, b) belongs to the function f(x) = y

Then the function notation is to replace x by a and y by b

`f(a)=b`

Since the ordered pair (2, -2) belongs to f(x) = y

Then replace x by 2 and y by -2

Then it should be

`f(2)=-2`

The answer is f(2) = -2
