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).

Katy invests $18,000 at 14% simple interest for 1 year. How much is in the account at the end of the 1 year period? Answer: $___
Nitella [24]

Answer:

$20,520 at the end of the year

Step-by-step explanation:

A = P(1 + rt)

   A = Total Accrued Amount (principal + interest)

   P = Principal Amount

   I = Interest Amount

   r = Rate of Interest per year in decimal; r = R/100

   R = Rate of Interest per year as a percent; R = r * 100

   t = Time Period involved in months or years

P = $18,000

r = .14

t = 1

A = 18,000 (1+ ( .14 * 1 ) )

A = 18,000 (1 +.14)

A = 18,000 (1.14)

A = 20,520

$20,520 at the end of the year

torisob [31]
Minimum point of an absolute value function is when f(x) = 0
0 = <span>|2x - 1|
2x</span> - 1 = 0
2x = 1
x = 1/2

Minimum point is (1/2, 0)
