Question

John is working the function s(x). He found that s(2)=-6
Matthew is working with the function t(x). He found that t(2)=-6
The point (2,-6) lies on the graph of s(x) and t(x).
True or False?

Answer 1

looks like it to me

Answer 2

Can you explain to me why? Thanks!

Answer 3

If a point (x,y) is on a graph of a function f, it means that y=f(x).

That is true for both s and t in this case.
