Using the information that you've provided, I would say that Mr. Banks drove home at 5:15, but if you're asking what time he arrived home that would be at 6:30. :))
The one that doesn’t go through the origin
When you plug the equation into a graphing calculator the x-intercept is -5

2a^2+4a+1 is equivalent to 4a+4/2a*a^2/a+1
