Suppose f(x)=x^2/x+4 Find each of the following and simplify as appropriate. a) f(2)
b) f(3a)
c) the domain of f

Step-by-step explanation:

I think you mean f(x) = x^2/(x+4). The parentheses matter.

f(2) = 2²/(2+4) = 4/6 = ⅔

f(3a) = (3a)²/(3a+4) = 9a²/(3a+4)

x ≠ 4, because division by zero is undefined.

Domain of f in interval form: (-∞,4)U(4,∞)

answer: i can’t tell you that

step-by-step explanation:

if you was gonna solve for a, a is a   < -12
