Use a graphing calculator to find the zeros to be

1, 3, -3, -2

Answer 8

@jim_thompson5910 ???

Answer 10

the lower bound is -1 (supposedly)...so the smallest zero SHOULD be -1

but we get -3 as a zero

Answer 11

what does that mean then?? this statement is FALSE?? :) WAs i right>? :)

Answer 12

if I told you that I have a list of numbers and I gave you the smallest number...but you determined there was a smaller number (smaller than my "smallest" number), this would be equivalent to what we are doing

Answer 13

oh oaky :) so ???

Answer 14

what do we do now??

Answer 15

Example:

I have the list of numbers 1, 2, 3, 4. I claim that the smallest number is 1. So the lower bound of this list is 1.

BUT

say you find out that 0 is also in this list (and it was hiding somehow). This would make my claim false because 1 is NOT a lower bound (there's clearly something below the "smallest" number)

Answer 16

therefore it is FALSE right??

Answer 17

it is, using this reasoning

Answer 18
