Question

Given that (2,3) is on the graph of f(x),find the corresponding point for the function f(x) - 4

Answer 1

I would say (-8,3) would be the corresponding point.

Answer 2

Given that (2,3) is on the graph of f(x)

So, for x = 2, f(x) = f(2) = 3

Now, define another function g(x) such that

g(x) = f(x) - 4

So g(2) = f(2) - 4 = 3 - 4 = -1

Hence, corresponding point for the function f(x) - 4 is (2, -1)
