James is bowling and knocked down 4 out of 10 pins. what fraction of pins are not knocked down?

James knocked down 4 out of 10 pins which means he had 10 pins - 4 pins and now has 6 pins.
Those 6 pins represent the pins that weren't knocked down and that makes 6/10 the fraction of pins that are NOT knocked down.

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
