Function f gives the temperature, in degrees Celsius, t hours after midnight. Match each statement with an equation or expression that represents the statement.

The temperature

at 12 p. m. ↔

The temperature was the same at 9

a. m. and at 4 p. m. ↔

It was warmer at 9 a. m. than at 6 a. m. ↔

Some time after midnight, the

temperature was 24 degrees Celsius. ↔

Matches:

f (0)

f (9) = f (16)

f(12)

f (9) = f (4)

f (9) > f (6)

f (t) = 24
