Answer:
A) The amplitude of f is five times greater than the amplitude of g.
Explanation:
We know that amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2.
From graph we can see that amplitude of function f is 5 while amplitude of function g is 1.
Clearly 5 is five times than 1.
So first choice "A) The amplitude of f is five times greater than the amplitude of g." is true.
