Based on the graphs of f (x) and g(x), what must the domain of (f ⋅ g)(x)be?
Exponential function f of x increasing from the left in quadrant 3 asymptotic to the line y equals negative 4 passing through the point 0 comma negative 3 and 1 comma negative 2 and 2 comma 0 and the rational function g of x with one piece increasing from the left in quadrant 2 asymptotic to the line y equals 2 passing through the point 1 comma 3 asymptotic to the line x equals 2 and another piece increasing from the left in quadrant 4 asymptotic to the line x equals 2 passing through the point 3 comma 1 to the right asymptotic to the line y equals 2
{x ∈ ℝ}
{x ∈ ℝ | x ≠ 2}
{x ∈ ℝ | x ≠ –4, 2}
{x ∈ ℝ | x ≠ –4, 2, 4}
