A(x) = 3x+1 and b(x) = square root of x-4, what is the domain of (b•a)(x)
1 answer:
a(x) = 3x + 1
b(x) =
(b . a)(x) =
(b . a)(x) =
We know some things:
There's no square root of a negative number, so,
x - 4 ≥ 0
x ≥ 4
This way, we can say that the domain of (b . a)(x) is:
Dom (b . a)(x) = R ≥ 4
All real numbers higher or equal to 4.
