2.12.2: Composition of functions on integers. Consider three functions f, g, and h, whose domain and target are Z. Let f(x)=x2           g(x)=2x           h(x)=⌈x5⌉   (b) Evaluate (f ο h)(52) (c) Evaluate (g ο h ο f)(4)

Consider the function: g(x) = with the domain R\(9} (i.e. all real numbers except 9) and the image R\{1} (i.e. all real numbers except 1). Find the expression for the inverse function g(x). Select one: O (5+9x)/(x+1) O 5+9x (x-9)/(x+5) O not in the list (5+9x)/(x-1)

Consider the function: g(z) = with the domain IR\{8} (i.e. all real numbers except 8) and the image R\{1} (i.e. all real numbers I+10 except 1). Find the expression for the inverse function g(r). Select one: O not in the list O (10+8x)/(x-1) O 10+8x O (10+8x)/(x+1) O (x-8)/(x+10)
