Asequence is defined by the recursive function f(n+1)=f(n)-2

Find the vertex for the parabola given by the function ƒ(x) = −3x2 − 6x.

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
