Answer:
Step-by-step explanation:
f(2) = 6 (what multiplies 2 to equal 6?)*2 = 6
It seems like x gets multiplied by three. Let's check the next one:
f(-1) = -3
Ah ha! We were right. Let's check one more time:
2 * 3 = 6
-1 * 3 = -3
f(x) just means what is f when x is any number. This function that we covered above is: f(x) = 3x
It would take the car 5 hours to travel 300km.
Equation used to solve: (120÷2)×6
