Effect of a pole on the real axis: A pole on the real axis will result in a low pass behavior for the filter. Observe the magnitude response when a single pole is located at s = −2π, s = −20π, s = −200π, s = −2000π, and s = −20000π. In each case note when the magnitude response is 3 dB below the maximum value.

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
