Answer:
The equation in function notation is:
=
![f(q)=(1)/(2)s-(3)/(2)](https://img.qammunity.org/2021/formulas/chemistry/high-school/2scn13jk1508nljorn21rznoyp5enu481y.png)
Step-by-step explanation:
Given equation:
![6q = 3s-9](https://img.qammunity.org/2021/formulas/chemistry/high-school/e7jzalsmw54hica3yv4cfo24joisf77l5a.png)
Where q is the independent variable.
To write the equation in function notation we will do the following:
Step 1 : divide 6 on both sides:
![(6q)/(6)=(3s-9)/(6)](https://img.qammunity.org/2021/formulas/chemistry/high-school/t6oan5ixu777wog7gyegm7z66ky34kqkk1.png)
![q=(1)/(2)s-(3)/(2)](https://img.qammunity.org/2021/formulas/chemistry/high-school/w4oexxby1tk19vevnp28f0osriunwrmoeh.png)
The function notation will become:
![f(q)=(1)/(2)s-(3)/(2)](https://img.qammunity.org/2021/formulas/chemistry/high-school/2scn13jk1508nljorn21rznoyp5enu481y.png)
