=> f(0) = \frac{1}{2}^{0} + 1 => f(0) = 1 + 1 = 2 \\b) f(x) = \frac{1}{2}^{x} + 1 => f(1) = \frac{1}{2}^{1} + 1 => f(1) = \frac{1}{2} + 1 = \frac{3}{2} \\c) f(x) = \frac{1}{2}^{x} + 1 => f(2) = \frac{1}{2}^{2} + 1 => f(2) = \frac{1}{4} + 1 = \frac{5}{4}\\d) f(x) = \frac{1}{2}^{x} + 1 => f(3) = \frac{1}{2}^{3} + 1 => f(3) = \frac{1}{8} + 1 = \frac{9}{8} \\e) f(x) = \frac{1}{2}^{x} + 1 => f(-1) = \frac{1}{2}^{-1} + 1 => f(-1) = 2 + 1 = 3\\[/tex]
