I got -4 but I don't know if that's right.

Answer 1

the answer is 4

Explanation:

maximum= 1 minimum= -7

1-(-7)/2= 8/2= 4

Answer 2

amplitude = 4

Explanation:

the amplitude is the maximum subtract the minimum divided by 2

maximum = 1 and minimum = - 7

amplitude =
`(1-(-7))/(2)` =
`(8)/(2)` = 4
