Answer:
C. -∞ < x < ∞
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see that our x-values can be any number. Therefore, we have all real numbers as our domain:
(-∞, ∞) or -∞ < x < ∞
X/2 = 8
▶ ️2 = 8 × X. (transposing X to RHS )
▶️ 2 = 8X
▶ ️X = 8/2. (transposing 2 to RHS )
▶️ X = 4
hence the value of X is 4.
Answer:
380
