f(x)=x+4 is the answer

(x+4)=0
x=4

Is there a question ?

btw, if x+4 = 0
x = -4 , not 4

To find the value of x that corresponds to the equation f(x) = x + 4, we need to solve for x. In this case, we can do this by setting the equation equal to zero and isolating x.

Step 1: Given f(x) = x + 4
Step 2: Set the equation equal to zero: x + 4 = 0
Step 3: To isolate x, we need to get rid of the +4 term. We can do this by subtracting 4 from both sides of the equation: x + 4 - 4 = 0 - 4
Step 4: Simplify the equation: x = -4

Therefore, the solution to the equation f(x) = x + 4 is x = -4.
