(Simplify your answer. y

Step-by-step explanation:

unit place can be filled with 3,5,7,9

number of ways=4

tens place can be filled  with 2,3,5,7,8,9

number of ways=6

Hundreds place canbe filled by 2,3,5,7,8,9

number of ways=6

thousands place can be filled by 2,3,5

number of ways=3

total number of ways=3×6×6×4=432 ways.

total number of digits=432

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)
