The first two deal with temperature, its continuous in both cases because temperature cannot change in an instant. The current is also continually circulating through the circuit without breaks (until you turn it off).

Altitude above sea level can have jump discontinuity at a cliff, or removable discontinuity at very deep hole. The cost of a taxi can have jump discontinuity if you’re not moving (The meter runs as the car uses gas, not based on distance traveled, the cost still raises if you make a stop).

Those are the only two that will change at a gradual rate without skipping values.

CONTINUOUS…each time can have only one temp

NOT CONTINUOUS…only defined for positive values

The current in the circuit for the lights in a room as a function of time.
CONTINUOUS…each time can have only one amperage measurement
