## vera_ewing one year ago What are the amplitude and the midline?

1. vera_ewing

2. vera_ewing

It's B right?

3. freckles

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

4. freckles

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

5. vera_ewing

Highest y value is 3 Lowest y value is -1

6. vera_ewing

Oh the answer has to be A then, right?

7. freckles

so midline is y=(3+(-1))/2 which is y=1 so how far is the max=3 from y=1?
