Question

Point A is at (4,5) and lies on the graph of quadratic function f.

If g(x) = f(2x), determine the location of this point on the graph of function g.

Answer 1

Given that point (4, 5) lies on a quadratic graph f.

The graph of g(x) = f(2x) means that the new graph takes the input of half the corresponding point from the old point.

Therefore, the location of the point (4, 5) in the new graph is given by (4/2, 5) = (2, 5).
