for the function y = f(x) what is the ordered pair for the point on the graph when x= b-2?

Question

(b - 2, f(b - 2))
(x, f(b))
(x, b-2)
(b - 2, f(b))***

Please help!!! :/

Answer 1

Replace x with , b - 2

Firs coordinate is x.

In this case :

b - 2

Second coordinate is :

y = f ( x ) = f ( b - 2 )

So :

b - 2 , f( b - 2 )
