The value of function x when r(x) = -4 based on the information will be 0.
It should be noted that a function is used in mathematics to show the relationship that exists between tow things that are illustrated.
In this case, the function that is given is:
x+ 4
Therefore, when the value is replaced by -4. This will be:
r(-4) = x + 4
r(-4) = -4 + 4
r(-4) = 0
Therefore, the value of function x when r(x) = -4 based on the information will be 0.
