Question

What are the amplitude and the midline?

Answer 1

It's B right?

Answer 2

can you tell me what is the highest y value?
can you also tell me what the lowest y value is ?

Answer 3

\[\text{ midline is given by } y=\frac{max+min}{2}\]
then to find the amp find either tell me how far max is from the midline
or how far min is from the midline

Answer 4

Highest y value is 3
Lowest y value is -1

Answer 5

Oh the answer has to be A then, right?

Answer 6

so midline is y=(3+(-1))/2
which is y=1

so how far is the max=3 from y=1?

Answer 7

Thanks I'm working on something like this too

Answer 8

2?

Answer 9

yep so
B was right
