Y = a sin b x
amplitude = a
period = 2π /b.
<span>y = 6 sin x
a = 6
b = 1
</span>
a, the amplitude, represents the highest point a graph reaches;
a = 6
The period represents the length of a cycle-
the period = 2π /b = 2π/1 = 2π
To find a percent from a decimal, you multiply the decimal by 100. So, the answer would be A.
the second one best represents f(x)=2|x|
