Definition
Functions have zeros or x-values that generate function values equal to zero.
Equations have roots or solutions that can be substituted into the polynomial in order to generate a value equal to zero.
Given:
![f(x)\text{ = -}\frac{1}{3}\sqrt[]{x}\text{ + 3}](https://tex.z-dn.net/?f=f%28x%29%5Ctext%7B%20%3D%20-%7D%5Cfrac%7B1%7D%7B3%7D%5Csqrt%5B%5D%7Bx%7D%5Ctext%7B%20%2B%203%7D)
To convert this to an equation, we set f(x) equal to zero i.e

The resulting equation is:
Answer:
20 45¢ stamps
Step-by-step explanation:
Since 100¢ = $1,
