Find the domain of the following piecewise function

r-ruslan [8.4K]

The domain of the function will be [-4, 6). Then the correct option is B.

The complete question is attached below.

<h3>What are domain and range?</h3>

The domain means all the possible values of x and the range means all the possible values of y.

The function is given below.

$f(x) = \left\{\begin{matrix}x+4, & if & -4\leq x < 3 \\\\2x-1, & if & 3 \leq x < 6 \\\end{matrix}\right.$

Then the domain of the function will be [-4, 6).

Then the correct option is B.

More about the domain and range link is given below.

loris [4]

Answer:

$250

Step-by-step explanation:

The formula for simple interest is I = PRT, where I= interest earned or paid, P = principal deposited or borrowed, R = interest rate as a decimal, and T = time in years.

I = PRT

I = (1000)(0.05)(5)

I = 250
