If we know that f(-4) = 8, then what (x, y) point must lie on the graph y = f(x)?.
The point is (-4, 8)
For a given function y = f(x), all the points (x, y) on the graph are of the form:
(x, y) = (x, f(x))
So if we know that:
f(-4) = 8
Then we know that the point:
(-4, f(-4)) = (-4, 8)
Must lie on the graph of y = f(x)
Then the correct answer is (-4, 8)
