Y = 3√(x-1).
Constraint: the radicand (x-1) ≥ 0 or x≥ 1
So the domain of this function is all Real for x ≥ 1
{x∈ R/x≥1}

Solution:

The given function is , y=3 \sqrt{x}-1

Domain means, those values of y, for which x is defined.

As,  \sqrt{x} is defined for positive real number, that is from [0, ∞]→→Called closed interval.

So, Domain of function  y=3 \sqrt{x}-1 is [0 ,∞]

Answer:

She will be charged $180 once lets the account go past 6 months before making a payment.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P

In this question:

If she pays within 6 months, she is not charged any interest.

However, if after 6 months she has not paid the balance, she is charged 20% interest for this period.

Barbara financed a new bedroom set at the furniture store for $1,800.

This means that P = 1800

20 percent interest

This means that I = 0.2

How much interest will she be charged once she lets the account go past 6 months?

6 months is half a year, so this is E when T = 0.5

E = P*I*t

E = 1800*0.2*0.5

E = 180

She will be charged $180 once lets the account go past 6 months before making a payment.
