Question

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting

parabola is (-6, -3). What is the vertex of the function defined as
g(x) = -f(x) + 3?

Answer 1

(6, 6).

Explanation:

The negative before f(x) reflects f(x) in the x-axis so this makes the new vertex equal to (-6, 3), then the + 3 translates it up 3 units so the required vertex is

(-6, 6).
