Answer:
![h(t)=x+0.46t](https://img.qammunity.org/2021/formulas/mathematics/college/76qxffmwelzro2nsru5jgdew8x0gpqy1sa.png)
Explanation:
-Let t denote time and h(t) be the function that denotes the temperature after time t
-Also, let's take x°F to be the initial temperature of the vinegar.
Since, the temperature increases by 2.3°F every 5 minutes, we determine the rate of change per minute:
![\bigtriangleup=(2.3)/(5)\\\\=0.46\textdegree F](https://img.qammunity.org/2021/formulas/mathematics/college/ukcrgajkob3qqgqjl2sg2ewlq3kzv6aaf1.png)
The situation can thus be expressed as:
![h(t)=x+2.3(t)/(5)\\\\h(t)=x+0.46t](https://img.qammunity.org/2021/formulas/mathematics/college/28pzuecerb2yx4qhgu9tesomjrm4dnatpc.png)
