You need to replace the coordinates given after dilating them or stretching the parabola.
For this case we have the following function:

The first thing you should do is graph the function to see the behavior.
When observing the graph (in the attached image) we observe that the following point belongs to the graph:

To prove it, let's evaluate the point in the function:

The equation is fulfilled and therefore the point belongs to the graph.
Answer:
(6.2, 7.4)
See attached image
9 million and 9 hundred thousand
9,000,000
and 900,000
The domain of the graph is less than or equal to 0.
Answer:
B
Step-by-step explanation:
It's very easy
