Question

I would need help with matching the function with its graph (labeled I-VI) with A, B, and C, please? 

15. Match the function with its graph (labeled I–VI). Give reasons
for your choices.
(a) f(x, y) = |x| + [y|
(b) F(x, у) — |ху|
1
(c) f(x, y)
(d) f(x, y) = (x² - y²)²
1 + x? + y?
(e) f(x, y) = (x y)²
(f) f(x, y) = sin(\x| + |y|)
