Hey here is the question has a few parts to it. Let f(x)= (x-1)^1/2 and g(x)= 2x^2/x^2+1 a) State the domain and range of f using interval notation. b) State the domain and range of g using interval notation. (Hint: At x=0, g is 0. For x(cannot=0) it helps to write g(x)=2/1+1/x^2 and then stetch a plot of g. Since x^2>0 it follows that g(x_ is always below 2) c) Find and simplify the expression for y(x)=(g o f)(x) and state its domain and range in interval notation. d) Find and simplify the expression for z(x)=(f o g)(x) and state its domain and range in interval notation. for a) i sketched a graph and made an x/y chart and subbed numbers in. 2 1 5 2 10 3 then got the domain to be: X E R | x >= 2 and the Rang YE R | y >= 1 domain: (2, infinity] ? Range: (1, infitty] ? and for b i did that same thing with the x/y chart and i got domain: X E R Range: Y E R | y >= 0 the hard part here is that i dont know how to put either of them in "interval notation" and for that c) and d) i have no clue what y(x)=(g o f)(x) is asking me to do, and also z(x)=(f o g)(x) some help would be great ! thanks.
