To solve the equation $e^x - 10 = -21e^{-x}$ graphically, we first rearrange it to get all terms on one side: $e^x + 21e^{-x} = 10$. Then, we plot two functions: $y = e^x + 21e^{-x}$ and $y = 10$, and find their points of intersection. The correct answer, $\{1.946, 1.099\}$, represents the x-values of these intersection points, rounded to the nearest thousandth.
