Are these functions inverses of each other?

h(x) = -1/3x + 1/3
f(x) = -3x + 1

What is the vertex form of f(x) = x2 + 6x + 3

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex
