Answer:
8
Step-by-step explanation:
The amplitude is the coefficient of the sine function: 8.
Answer:
8
Step-by-step explanation:
Amplitude is the onehalf of highest value minus the lowest value
since sine function has maximum 1 and minimum -1, then the highest value of f(x) is 8(1) - 3 = 5 and the minimum value is 8(-1)-3 = -11.
Therefore the amplitude is (1/2) ( 5 +11) = 8.
