Answer

Explanation:

Step1: Identificar la forma general

La forma general de una parábola en forma vertex es $y=a(x - h)^2+k$, donde $(h,k)$ es el vértice. Para $y=(x - 9)^2$, el vértice es $(9,0)$ y para $y=(x + 9)^2=(x-(- 9))^2$, el vértice es $(-9,0)$.

Step2: Analizar el cambio en el eje x

El cambio en la coordenada $x$ del vértice es $-9-9=-18$. Esto significa que el vértice se mueve 18 unidades hacia la izquierda.

Answer:

The graph moves left 18 units.
