I'm not 100% sure about this because this unit confused me but...

if you put it in your graphing calculator or in desmos, you can see that the first positive x -intercept (which is a point that is on the x-axis) is somewhere around one but it's not 1.571!! (other person is wrong!)

that point is (0.571, 0) so it's the first option
