Functions f(x) and g(x) are composed to form h (x) = StartRoot x cubed minus 2 EndRoot. If f (x) = StartRoot x + 2 EndRoot and g

So the equation of the red graph is already given to us: . I assume you meant the blue graph?
We can use the vertex form: , where
is the vertex. (We can ignore
because
is 1 for this graph.) Remember that the vertex is the maximum or minimum of a parabola and the point that the line of symmetry passes through. For f(x) the vertex is (0,0).
The vertex for is at
on the coordinate plane. (4 left, 2 down)
Plug into the vertex form:
The double negative becomes a positive, and then you're done:
