Answer:
The vertex of transformed parabola is:
(6,-3)
Step-by-step explanation:
We are given a equation of parabola as:

Now we have to transform the parabola

by shifting 7 units to the right and 5 units down.
We know that if a parabola is shifted 7 units to the right and 5 units to the down then the equation of the transformed parabola is given as:
<em>We know that for any equation of parabola of the type:</em>
<em>
</em>
<em>The vertex of parabola is:</em>
<em>(h,k)</em>
Now,the vertex of the transformed parabola is:
(6,-3)
