7? *
A. It makes the graph really wide.
B. It makes the graph really narrow.
C. It makes the graph shift up 5 above the origin.
D. It makes the graph shift down 5 below the origin.

Answer 1

Answer:

B. It makes the graph really narrow.

Step-by-step explanation:

$\displaystyle Y = A[X - H]^2 + K$

In the Vertex Formula, any fraction you store in for A will result in a vertical shrink, widening the graph, whereas any whole number you store in for A will result in a vertical stretch, narrowing the graph.
