HELP PLEASE

1. If f(a) = 3a – a2, which of the following are not true statements?
Select all that apply.

f(-5) = -40
f(4) = -4
f(-1) = 2
f(0) = 3
f(3) = 0

2. Your savings account has a balance of $125. You add $22 a month to this balance.
Which equation shows your balance, b, in m months?
b( m) = $125 m + $22
m( b) = $125 b + $22
m( b) = $125 + $22 b
b( m) = $125 + $22 m

3. Find x, if f(x) = 12 and f(x) = 3x.
