Question

Given that (-5,8)is on the graph of f(x) find the corresponding point for the function f(x)-2

Answer 1

I never came across a question like this one. Time to reason my way to the answer.

We know that f(x) = y.

In the point given, y = 8.

So, f(x) - 2 = y - 2 = 8 - 2 = 6.

The corresponding point should be (-5, 6).
