Determine the amplitude of the function y= -1/2 cos x. a. -1 b. -1/2 c. 1/2 d. 2

i dont understand the question? ?

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
