Quadratic Function Math Question

Question

A quadratic function y=f(x)

y=f(x) is plotted on a graph and the vertex of the resulting parabola is (-6, 4)(−6,4). What is the vertex of the function defined as g(x)=-f(x)-2g(x)=−f(x)−2?

Answer 1

f(x)= a(x+6)^2 +4

g(x)=-a(x+6)--4-2

g(x) vertex =(-6,-6)
