the roots of the polynomial means what are the values of x when y = 0
triciaal
  • triciaal
where does the graph cross the x-axis?
anonymous
  • anonymous
is one of them 6 and -1.1?

hint check all that apply more than one place
triciaal

yes

what about 2?
anonymous
  • anonymous
there is no 2 only 2.4
anonymous
  • anonymous
what about 1 ?
triciaal
  • triciaal
i would put 2,4 remember the polynomial is a continuous line cross it with the x-axis and read the points of intersection
anonymous
  • anonymous
should -1.7 be also one of them since the dot is in -1.1 ?
triciaal
  • triciaal
not to me -1.7 would be very close to -2 the line crosses just past -1 so the root is -1.1
anonymous
  • anonymous
4.3 would not be one of the roots because there nothing between there am i correct ?
anonymous
  • anonymous
so far my answers would be 6 , -1.1, and 2.4 correct
triciaal
  • triciaal
the roots are the x points where the graph touches the x-axis
triciaal
  • triciaal
yes
