5. (Sydsaeter et al (2016, p. 96), Exercises for Section 4.2, Question 14.) Consider the function f(x) = (x-2) (a) Find the domain of this function. (b) Show that 5 belongs to the range of this function. (Hint: Find a value for a such that f (T) = (1-2) (3:+6) = 5. (c) Show that 3 does not belong to the range of this function. 6. (Sydsaeter et al (2016, p. 411), Exercises for Section 11.1, Question 6.) Find the domains of the following functions and then illustrate those domains in the (x, y)-coordinate-plane. (a) f(x, y) = zty (b) f(x, y) = V2 - (x2 + yz). (c) f(x, y) = V(4 -x2 - y?) (x2 + y? - 1)
