Answer:
-48 ÷ 12
Step-by-step explanation:
account balance changed over a year = -$48
In a year, there are 12 months. Above statement can also be written as
account balance changed in 12 months = -$48
we have to find monthly change, so we divide LHS and RHS by 12
account balance changed in 12 /12 months = -$48/12
Thus, account balance changed in 1 months = -$48/12
which is represented option 4 i.e -48 ÷ 12

y=-2
y=-2, y=-1
I hope this helps you
f(2)=2^2+2.2-1=4+4-1=7
f (-2)=(-2)^2+2. (-2)-1 =4-4-1= -1
f (3)=3^2+2.3-1=9+6-1=14
f (-3)=(-3)^2+2. (-3)-1=9-6-1=2
