What is the square root of 4/225

LuckyWell [14K]

2 / 15

This is simpler than you think. Just take the square root of the denominator and of the numerator and stick it back into fraction form. The square root of 4 is 2 and the square root of 225 is 15. Voila: 2 / 15.

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).
