Answer and Explanation:
A parent function is the simplest form of a family of functions.
Let's go ahead and list the parent functions of each of the given functions;
*A quadratic parent function is generally given as;
![y=x^2](https://img.qammunity.org/2023/formulas/mathematics/college/1ch5n55tacdusoaz2xqjwppl7gqbo47w29.png)
*The greatest integer parent function is generally given as;
![y=\lbrack x\rbrack](https://img.qammunity.org/2023/formulas/mathematics/college/m3qhlerhkmu8cdntal59xvwsd4j95njv53.png)
*A square root parent function is generally given as;
![y=\sqrt[]{x}](https://img.qammunity.org/2023/formulas/mathematics/college/z3kevgn2c29nk34ba6n3a5xhvm9rhyzg0b.png)
*A reciprocal parent function is generally given as;
![y=(1)/(x)](https://img.qammunity.org/2023/formulas/mathematics/high-school/k0etrkbb74ccnpmvs5067lnrpcwe8h2ytl.png)
