If the point P is on the graph of a function f, find the corresponding point on the graph of a given function.

Question

P (0,5) y = f ( x + 2 ) - 1

Answer 1

Since we know f(0), x+2 must be 0.

y(-2) = f(0)-1 = 4

Answer 2

I understand how you get x to be -2, but I still don't get how y became 4

Answer 3

f(0) = 5, since P is on the graph of f(x).

y(-2) = f(0) - 1
