d. all of the above.
Proof -
All the Given options are correct to study the validity of a hypothesis test.
So,
The Correct option is - d. all of the above.
To find area you
Multiply base times height.
Bh=A
So multiply the base times the height of the graph?
So 6 times 6 equals area.
Of course since we are dealing with the 4 quadratics 6 can be negatives or positive.
Whether it’s negative or not area is area.
If you’re finding the coordinates shapes area, sorry I have no idea
I am doing this too but mines definitely different
