Question

Brittany was tracking the increasing temperature in the morning. At 8 a.m. it was 68 degrees Fahrenheit. At 10 a.m. it was 74 degrees Fahrenheit. If Brittany made the function f(x) = 3x + 36, what would the 36 represent? The temperature at midnight

The rate the temperature was increasing

The length of time she recorded for

The total change in degrees

Answer 1

36 is the y intercept, the value for the function when x = 0. In this function the x's are the times and the y's are the temperatures. so in this scenerio, when x = 0, the time would be midnight

Answer 2

The temperature at midnight

Step-by-step explanation

The function that Brittany came up with is a linear equation. If the graph his graph was of temperature against time, then 36 would represent the Y-intercept.

In this case, it must be the time Brittany started tracking the increase in temperature. We are told that he start in the morning. This must be the midnight.

So, the answer is The temperature at midnight
