What is the domain of the function y= square root x?

1 answer:

5 0

The domain of a function is the set of values of the independent variable for which the function is defined. The square root function is defined for all non-negative real numbers. So, ...

The domain of

y = √x

is all real numbers greater than or equal to zero. (x ≥ 0)

_____

In some cases, there may be other limits on the domain of a function. A function may be defined for all values of mass, for example, but is of no practical use for values of mass greater than the mass of the known universe (or planet Earth, perhaps).

Ber [7]

Answer:

Step-by-step explanation:

The simple interest formula is

I = Prt, where I is the interest earned, P is the initial investment, r is the interest rate in decimal form, and t is the time in years. We have that after 2 years, 9000 has turned into 10440. That means that the total interest earned was 10440 - 9000 = 1440

I = 1440

P = 9000

r = ?

t = 2

Filling in we have

1440 = 9000(r)(2) and

1440 = 18000r so

r = .08

As an interest rate, we multiply this by 100 to get 8%

The first number is what percent of the second ? x of y

mel-nik [20]

I really don't know what you mean, but to find the percent, multiply x and y and then divide your answer by 100, or move your decimal place to the left twice. hope that helped :)
