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).

An organization will give a prize to a local artist. The artist will be randomly chosen from among 10 painters, 3 sculptors, and
Fofino [41]

The probability is 8/18 or 44%.


Since there are 3 sculptors and 5 photographers, and the question is asking for either a sculptor or photographer, you add them together. There are a total of 18 artists, and the probability is the chance of a certain thing happening over the total amount of things that can happen (i.e. a coin landing on heads is 50%).

The answer would be 8/18.
