The second derivative represents acceleration, so the larger the a value the faster the increase of velocity and accordingly a quicker progression towards positive or negative infinity.

hope this helps
brainliest appreciated
good luck! have a nice day!
Take all the x values and make them y value, take all the y values and make them x values.
