<h3>What is function?</h3>
Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
According to the question,
The given function is

Here f(x) = -12
Substitute f(x) and solve for x

By subtracting 3 on both sides


By dividing -5 on both sides

We get absolute values for the function.

By subtracting 1 on both sides

Therefore, the values of x are 2 and - 4 of the given function f (x) =-5|x+1| +3
