Question 254469
Given f(x)=sin x, g(x)= 1/x and h(x)=/x/ 
a) state the equation that represents y=h(g(f(x)))
ans:
y = {{{abs(1/sin(x))}}}
b) Describe what each composition does in order that its applied.
g(f(x)) put the f(x) into the g(x) function to get 1/sin(x)
h(g(f(x))) puts 1/sin(x) into abs to get abs(1/sin(x))
c) Sketch the curve won the interval -2(pi)< or = x <or= 2(pi)


{{{ graph( 300, 200, -2*pi, 2*pi, -5, 5, abs(1/(sin(x)))) }}}
