Answer 2

`x=2` and
`x=-4`

Explanation:

`f(x)= -5|x+1| +3`

Given f(x)= -12

Replace f(x) by -12 and solve for x

`-12= -5|x+1| +3`

Subtract 3 on both sides

`-15= -5|x+1|`

Divide both sides by -5

`3= |x+1|`

Now make two equations

`x+1=3` and
`x+1=-3`

Subtract both sides of equation by 1

`x+1=3` and
`x+1=-3`

`x=2` and
`x=-4`
