A function is a relationship that each input (element of the domain) is paired with exactly one output (element in the range).
In function notation, f(x), the “x” is the input and the entire “f(x)” represents an output.
That means the last two options are wrong. They’re purposely switched up in what they say.
The correct answer is the second one, because that one is saying “each input will be paired with exactly one output.”
Answer:
<em>The threatest whole number in the interval is 2</em>
Step-by-step explanation:
<u>Numbers and intervals</u>
We are given the interval of numbers between -16 and 2. Since it's not specified, both endpoints of the interval are not included.
If we consider the interval as real numbers, then there are infinitely many numbers there, like -15, -12.56, -8, -2pi, 0.02, 1.99.
If we are restricted to only whole numbers, then we get a limited set of the numbers: {-15, -14, -13, -12,....,1}
Note the greatest number at the right endpoint of the interval is 1, since we are not including 2.
The threatest whole number in the interval is 2
we are given
![f(x)=\sqrt[3]{x+2}](https://tex.z-dn.net/?f=%20f%28x%29%3D%5Csqrt%5B3%5D%7Bx%2B2%7D%20%20)
Firstly , we set f(x)=y
![y=\sqrt[3]{x+2}](https://tex.z-dn.net/?f=%20y%3D%5Csqrt%5B3%5D%7Bx%2B2%7D%20%20)
now, we can switch x and y
![x=\sqrt[3]{y+2}](https://tex.z-dn.net/?f=%20x%3D%5Csqrt%5B3%5D%7By%2B2%7D%20%20)
now, we can solve for y
![x^3=(\sqrt[3]{y+2})^3](https://tex.z-dn.net/?f=%20x%5E3%3D%28%5Csqrt%5B3%5D%7By%2B2%7D%29%5E3%20%20)
so, our inverse function is
