Answer:
The function rule can be written as: f(x) = 2x-3
So, when we input 3, we replace all of the x's for 3's and have: f(3) = 2(3)-3.
This simplifies to be: f(3) = 3, meaning that 3 is the output.

Answer: The average speed of the rollercoaster is 30 meters per second.
Step-by-step explanation:
Hi, since:
Speed rate = distance /time
To answer this question we simply have to divide the length (distance) of the rollercoaster (3,000 meters) by the time spent on traveling it (100 seconds)
Mathematically speaking;
3000 meters / 100 seconds = 30 meters per second
The average speed of the rollercoaster is 30 meters per second.
Substitute x=1 into the equation (1,-2)
