Find the domains of the functions defined by the following formulas, and then draw these domains in the xy-plane: (a) (2 points) √ 1 − xy (b) (2 points) p x 2 + y 2 − 1 p 9 − x 2 − (y − 1)2.

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
