ANSWER
The resulting parabola in vertex form is:

EXPLANATION
The original equation of the parabola is given as

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:

This the equation of the transformed parabola.
Its vertex is now at (4,-3).
Answer:
C. a = 6 , b = 2√10
Step-by-step explanation:
Similarity triangles so
a/2 = 18/a
a^2 = 36
a = 6
b^2 = 2^2 + 6^2
b^2 = 4 + 36
b^2 = 40
b = 2√10
Answer
a = 6 , b = 2√10
