hi i really need help on this assignment.

& this is the data i have to use for the information

Below is the data collected in class for the "Heat It, Then Cool It", application problem.

I am listing the data as ordered pairs, where the first coordinate represents the Time in seconds, and the second coordinate represents the Temperature in degrees Fahrenheit.

( 0 , 86.9 ) , ( 5 , 150.9 ) , ( 10 , 165.6 ) , ( 15 , 170.3 ) , ( 20 , 172.0 ) , ( 25 , 172.3 ) , ( 30 , 172.5 )

( 35 , 172.6 ) , ( 40 , 85.9 ) , ( 45 , 59.1 ) , ( 50 , 48.6 ) , ( 55 , 44.8 ) , ( 60 , 43.1 ) , ( 65 , 42.3 ) , ( 70 , 41.7 )

It appears that the first part of the piecewise function should be written for t less than 35, and the second part for t greater than or equal to 35.

And remember, we said that the horizontal asymptotes were at y=173 and y=41.
