Answer:

$\huge\boxed{28\ and\ 7}$

Step-by-step explanation:

If the graph of the following parabola is shifted four units right and three units down, what is the resulting equation in verte

AURORKA [14]

ANSWER

The resulting parabola in vertex form is:

$(x - 4) = 4( {y + 3)}^{2}$

EXPLANATION

The original equation of the parabola is given as

$x = 4 {y}^{2}$

This parabola has its vertex at the origin.

If the graph of this parabola is shifted four units right and three units down, then the new equation is:

$(x - 4) = 4( {y + 3)}^{2}$

This the equation of the transformed parabola.

Its vertex is now at (4,-3).
