In this problem, we will cover interpreting a numerical example of a two -variable function in isolating data.
00:08
So we are given here to the left a table of values for temperature adjusted for wind chill.
00:16
And it's basically telling us what the temperature feels like based on two variables, wind speed in miles per hour, and the actual temperature in degrees fahrenheit.
00:31
And you can pick any value off the table and trace it back to any combination of the wind speed and temperature values given.
00:42
So if we wanted to isolate the data to a certain temperature, let's say in our first scenario, we're going to restrict our data to a temperature value of 20 degrees fahrenheit.
00:59
So i'm going to highlight 20 degrees.
01:02
And we must.
01:06
Note that wind speed is not restricted, so we're just going to copy every value of wind speed onto our second table.
01:25
And since our temperature is 20 degrees fahrenheit, that means we're going to be looking in this fourth column for all of our values for adjusted temperature.
01:41
So we're just going to transfer those values going down the column into our 3rd.
01:46
Table on the right, our first table on right.
01:49
So first we have 13...
