On Friday, the temperature was 82 degrees. The temperature changed by -2 degrees on Saturday, and then it changed by 5 degrees on Sunday. What was the temperature on Sunday? Explain how the temperature changed using integers.

Notice that the shape of the temperature graph for Exercises 81 through 84 is similar to a parabola (see Section 8.5). In fact, this graph can be approximated by the quadratic function $f(x)=3 x^{2}-18 x+57,$ where $f(x)$ is the temperature in degrees Fahrenheit and $x$ is the number of days from Sunday. Use this function to answer. Use the given function and the quadratic formula to find when the low temperature was $35^{\circ} \mathrm{F}$. [Hint: Let $f(x)=35$ and solve for $x .]$ Round your answer to one decimal place and interpret your result. Does your answer agree with the graph on the previous page?
