I. let f(x) = 2x – 1, g(x) = 3x, and h(x) = x2
+ 1. compute the following:

1. f(g(-1))
2. f o h(3)
3. g(f(-5))
4. h(f(x))
5. f(f(x)) 6
. h o g(x)

Add, subtract, multiply, or divide as indicated. list any restrictions for the variable(s) and simplify the answers when possible. 1) x-2 / x+5 + 3x / 2x-1 2) x+6 / x-6 - x^2 / x+6 3) x+9 / x-4 + x+2 / x^2-11x+28 4) x / x^2-64 + 11 / 2x^2+11x-40 5) 5 / x + 11 / x-3 - x-4 / x^2+2x-15
