![f(x) = \sqrt[3]{x - 3}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B3%5D%7Bx%20-%203%7D)
The domain of a function are the values of
that you can plug into the function
.
Values inside of a root must be non-negative, which means that
must be greater than or equal to zero. We can set up an equation to find the domain:


With this, we know the domain of the function is
.
The range of a function are the values that
can have. Since the equation is a cube root, the value will always be non-negative, meaning the range of the function is
.
Answer:
$104.19
Step-by-step explanation:
We will use the compound interest formula to solve this:

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, lets change 5% into a decimal:
5% ->
-> 0.05
Now, plug the values into the equation:


After 3 years, Maria will have $104.19
