Nah

Step-by-step explanation:

Definition of a function:

a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output!

According to this, i.e. you have multiple y for x = -2, -1, 0, 1, 2, 3, 4

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
