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?

Answer 1

The temperature at midnight

The rate the temperature was increasing

The length of time she recorded for

The total change in degrees

Answer 2

@Preetha

Answer 3

Well, if you let \(x=0\) then \(f(x)=36\).

Answer 4

What does \(x=0\) represent?

Answer 5

would it be d @wio

Answer 6

Well, d doesn't quite make sense

Answer 7

@radar @ranga

Answer 8

its it b @ranga

Answer 9

The function f(x) = 3x + 36 does not quite fit the data that is given.
But the closest answer is a) because 36 is the value of the function at x = 0 and x can be the time since midnight and x = 0 represents midnight.
So 36 is the temperature at midnight.
