Question

quinn plugs in her electric car to charge it. the function f(x) gives the number of minutes remaining until the car is fully charged. it depends on x, the number of minutes the car has been charging. what does f(200) < 10 tell you? after 200 minutes, the car is less than 10% charged. after 200 minutes, the car is within 10 minutes of being fully charged.

Explanation:

The function \( f(x) \) represents the number of minutes remaining until the car is fully charged. When \( x = 200 \) (200 minutes of charging), \( f(200)<10 \) means the value of the function (minutes remaining) is less than 10. So it's about the time remaining, not the percentage charged.

Answer:

After 200 minutes, the car is within 10 minutes of being fully charged.
