Answer

A: $ f(-4) = 1 $ B: $ f(11) = 4 $ C: $ f(4) = 3 $ D: $ f(x+\Delta x) = \sqrt{x+\Delta x + 5} $

Work Step by Step

A: $ f(-4) = \sqrt{-4+5} $ $ f(-4) = \sqrt{1} $ $ f(-4) = 1 $ B: $ f(11) = \sqrt{11+5} $ $ f(11) = \sqrt{16} $ $ f(11) = 4 $ C: $ f(4) = \sqrt{4+5} $ $ f(4) = \sqrt{9} $ $ f(4) = 3 $ D: $ f(x+\Delta x) = \sqrt{x+\Delta x + 5} $
