For each of the following, prove that f is 1-1 on E and find f(E). a) f(x)
Question:
a) f(x) = 3x - 7, E = R
β) f(x) = el/x, E = (0, ∞)
γ) f(x) = tan x, E = (π/2, 3π/2)
δ) f(x) = x2 + 2x - 5, E = (-∞, -6]
e) f(x) = 3x - |x| + |x - 2|, E = R
ζ) fix) = x/(x2 + 1), E = [-1, 1]
b) Find an explicit formula for f-1 on f(£).
