I have failed at my first two attempts at these. I am looking for help for the third try at this.Derivation of Selected LinearizationsDerive the following linearizations in detail:1. Show that the linearization of ƒ(x) = (1 + x)k at x = 0 is L (x) = 1 + kx.2. Find the linearization of ƒ(x) = √x + 1 + sin(x) at x = 0.3. How is the linearization you just found in Step 2 related to the linearizations of √x + 1 and sin(x) at x = 0?
