If a(x) = 3x + 1 and b (x) = square root of x-4, what is the domain of (b o a)(x)
Monica [59]

( 1, ∞)  is the domain of (b o a)(x)

<h3>What is Function?</h3>

A function is defined as a relation between a set of inputs having one output each.

According to the question,

a(x) = 3x + 1 \\\\b (x) =\sqrt{x+4}

To find the domain of the composite function,

(b o x) (x) = b(a(x))\\\\(b o x) (x) = b(a(3x-1))\\\\(b o x) (x) = \sqrt{3x+ 1 -4} \\\\(b o x) (x) = \sqrt{3x -3}\\\\

Therefore,

3x - 3 \geq 0\\3x \geq 3\\x \geq 1\\\\

Hence , [ 1, ∞ ] is is the domain of (b o a)(x).
