3. Consider each function f : D→ R below, where D is its (natural/largest possible)
domain. In each case, (i) say whether or not the given values are in the range of
f; (ii) determine the range of f; (iii) justify your answer to part (ii) in each case
by describing a point (x, y) such that f(x, y) = c for each c in the range.
(a) f(x,y) = 32. 0, 1, -2.
3x+y

Expert Solution

Step 1: Given

The given function is $f open parentheses x comma y close parentheses equals fraction numerator 3 over denominator 3 x plus y end fraction$ and D is its domain.

(i) The given values are $0 comma 1 comma negative 2$ , to determine whether the given values are in the range of $f$ .

(ii) To determine the range of $f$ .

(iii) To justify the answer to part (ii) in each case by describing a point $open parentheses x comma y close parentheses$ such that $f open parentheses x comma y close parentheses equals c$ for each $c$ in the range.
