15) For the functions y₁ = f(x) = csc(x) x 0 <x< y = f₂(x) = csc (x + 1) o) Draw the functions. q) find their domain and Range. 0 <x< s) Are they decreasing or increasing? u) Find (fi + 2)(x) w) Have they an invesre, find it if any b) What are their types. d) Are they odd or even or neither? f) Find f-f hj Find (fi/f₂)(x)
